-    (#)Initialize the ADC low level resources by implementing the HAL_ADC_MspInit():
-       (##) Enable the ADC interface clock using __ADC_CLK_ENABLE()
-       (##) ADC pins configuration
-             (+++) Enable the clock for the ADC GPIOs using the following function:
-                   __GPIOx_CLK_ENABLE()  
-             (+++) Configure these ADC pins in analog mode using HAL_GPIO_Init() 
-       (##) In case of using interrupts (e.g. HAL_ADC_Start_IT())
-             (+++) Configure the ADC interrupt priority using HAL_NVIC_SetPriority()
-             (+++) Enable the ADC IRQ handler using HAL_NVIC_EnableIRQ()
-             (+++) In ADC IRQ handler, call HAL_ADC_IRQHandler()
-      (##) In case of using DMA to control data transfer (e.g. HAL_ADC_Start_DMA())
-             (++) Enable the DMAx interface clock using __DMAx_CLK_ENABLE()
-             (++) Configure and enable two DMA streams stream for managing data
-                 transfer from peripheral to memory (output stream)
-             (++) Associate the initilalized DMA handle to the CRYP DMA handle
-                 using  __HAL_LINKDMA()
-             (++) Configure the priority and enable the NVIC for the transfer complete
-                 interrupt on the two DMA Streams. The output stream should have higher
-                 priority than the input stream.

-                        ##### How to use this driver #####
-  ==============================================================================
-    [..]            
-      (#) Enable the CAN controller interface clock using 
-          __CAN1_CLK_ENABLE() for CAN1 and __CAN1_CLK_ENABLE() for CAN2
-      -@- In case you are using CAN2 only, you have to enable the CAN1 clock.
-       
-      (#) CAN pins configuration
-        (++) Enable the clock for the CAN GPIOs using the following function:
-             __GPIOx_CLK_ENABLE()   
-        (++) Connect and configure the involved CAN pins to AF9 using the 
-              following function HAL_GPIO_Init() 
-              
-      (#) Initialise and configure the CAN using CAN_Init() function.   
-                 
-      (#) Transmit the desired CAN frame using HAL_CAN_Transmit() function.
-           
-      (#) Receive a CAN frame using HAL_CAN_Recieve() function.

-     *** Polling mode IO operation ***
-     =================================
-     [..]    
-       (+) Start the CAN peripheral transmission and wait the end of this operation 
-           using HAL_CAN_Transmit(), at this stage user can specify the value of timeout
-           according to his end application
-       (+) Start the CAN peripheral reception and wait the end of this operation 
-           using HAL_CAN_Receive(), at this stage user can specify the value of timeout
-           according to his end application 
-       
-     *** Interrupt mode IO operation ***    
-     ===================================
-     [..]    
-       (+) Start the CAN peripheral transmission using HAL_CAN_Transmit_IT()
-       (+) Start the CAN peripheral reception using HAL_CAN_Receive_IT()         
-       (+) Use HAL_CAN_IRQHandler() called under the used CAN Interrupt subroutine
-       (+) At CAN end of transmission HAL_CAN_TxCpltCallback() function is executed and user can 
-            add his own code by customization of function pointer HAL_CAN_TxCpltCallback 
-       (+) In case of CAN Error, HAL_CAN_ErrorCallback() function is executed and user can 
-            add his own code by customization of function pointer HAL_CAN_ErrorCallback
- 
-     *** CAN HAL driver macros list ***
-     ============================================= 
-     [..]
-       Below the list of most used macros in CAN HAL driver.
-       
-      (+) __HAL_CAN_ENABLE_IT: Enable the specified CAN interrupts
-      (+) __HAL_CAN_DISABLE_IT: Disable the specified CAN interrupts
-      (+) __HAL_CAN_GET_IT_SOURCE: Check if the specified CAN interrupt source is enabled or disabled
-      (+) __HAL_CAN_CLEAR_FLAG: Clear the CAN's pending flags
-      (+) __HAL_CAN_GET_FLAG: Get the selected CAN's flag status
-      
-     [..] 
-      (@) You can refer to the CAN HAL driver header file for more useful macros

-      
-
-     -@- When the NVIC_PRIORITYGROUP_0 is selected, IRQ pre-emption is no more possible. 
-         The pending IRQ priority will be managed only by the sub priority.

-    *** How to configure Systick using Cortex HAL driver ***
-    ========================================================
-    [..]
-    Setup SysTick Timer for 1 msec interrupts.
-           
-   (+) The HAL_SYSTICK_Config()function calls the SysTick_Config() function which
-       is a CMSIS function that:
-        (++) Configures the SysTick Reload register with value passed as function parameter.
-        (++) Configures the SysTick IRQ priority to the lowest value (0x0F).
-        (++) Resets the SysTick Counter register.
-        (++) Configures the SysTick Counter clock source to be Core Clock Source (HCLK).
-        (++) Enables the SysTick Interrupt.
-        (++) Starts the SysTick Counter.
-    
-   (+) You can change the SysTick Clock source to be HCLK_Div8 by calling the macro
-       __HAL_CORTEX_SYSTICKCLK_CONFIG(SYSTICK_CLKSOURCE_HCLK_DIV8) just after the
-       HAL_SYSTICK_Config() function call. The __HAL_CORTEX_SYSTICKCLK_CONFIG() macro is defined
-       inside the stm32f2xx_hal_cortex.h file.
-
-   (+) You can change the SysTick IRQ priority by calling the
-       HAL_NVIC_SetPriority(SysTick_IRQn,...) function just after the HAL_SYSTICK_Config() function 
-       call. The HAL_NVIC_SetPriority() call the NVIC_SetPriority() function which is a CMSIS function.
-
-   (+) To adjust the SysTick time base, use the following formula:
-                            
-       Reload Value = SysTick Counter Clock (Hz) x  Desired Time base (s)
-       (++) Reload Value is the parameter to be passed for HAL_SYSTICK_Config() function
-       (++) Reload Value should not exceed 0xFFFFFF

-  ==============================================================================
-                      ##### DAC Peripheral features #####
-  ==============================================================================
-    [..]        
-      *** DAC Channels ***
-      ====================  
-    [..]  
-    The device integrates two 12-bit Digital Analog Converters that can 
-    be used independently or simultaneously (dual mode):
-      (#) DAC channel1 with DAC_OUT1 (PA4) as output
-      (#) DAC channel2 with DAC_OUT2 (PA5) as output
-      
-      *** DAC Triggers ***
-      ====================
-    [..]
-    Digital to Analog conversion can be non-triggered using DAC_Trigger_None
-    and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register. 
-    [..] 
-    Digital to Analog conversion can be triggered by:
-      (#) External event: EXTI Line 9 (any GPIOx_Pin9) using DAC_Trigger_Ext_IT9.
-          The used pin (GPIOx_Pin9) must be configured in input mode.
-  
-      (#) Timers TRGO: TIM2, TIM4, TIM5, TIM6, TIM7 and TIM8 
-          (DAC_Trigger_T2_TRGO, DAC_Trigger_T4_TRGO...)
-  
-      (#) Software using DAC_Trigger_Software
-  
-      *** DAC Buffer mode feature ***
-      =============================== 
-      [..] 
-      Each DAC channel integrates an output buffer that can be used to 
-      reduce the output impedance, and to drive external loads directly
-      without having to add an external operational amplifier.
-      To enable, the output buffer use  
-      sConfig.DAC_OutputBuffer = DAC_OutputBuffer_Enable;
-      [..]           
-      (@) Refer to the device datasheet for more details about output 
-          impedance value with and without output buffer.
-            
-       *** DAC wave generation feature ***
-       =================================== 
-       [..]     
-       Both DAC channels can be used to generate
-         (#) Noise wave 
-         (#) Triangle wave
-            
-       *** DAC data format ***
-       =======================
-       [..]   
-       The DAC data format can be:
-         (#) 8-bit right alignment using DAC_ALIGN_8B_R
-         (#) 12-bit left alignment using DAC_ALIGN_12B_L
-         (#) 12-bit right alignment using DAC_ALIGN_12B_R
-  
-       *** DAC data value to voltage correspondence ***  
-       ================================================ 
-       [..] 
-       The analog output voltage on each DAC channel pin is determined
-       by the following equation: 
-       DAC_OUTx = VREF+ * DOR / 4095
-       with  DOR is the Data Output Register
-          VEF+ is the input voltage reference (refer to the device datasheet)
-        e.g. To set DAC_OUT1 to 0.7V, use
-          Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
-  
-       *** DMA requests  ***
-       =====================
-       [..]    
-       A DMA1 request can be generated when an external trigger (but not
-       a software trigger) occurs if DMA1 requests are enabled using
-       HAL_DAC_Start_DMA()
-       [..]
-       DMA1 requests are mapped as following:
-         (#) DAC channel1 : mapped on DMA1 Stream5 channel7 which must be 
-             already configured
-         (#) DAC channel2 : mapped on DMA1 Stream6 channel7 which must be 
-             already configured
-       
-    -@- For Dual mode and specific signal (Triangle and noise) generation please 
-        refer to Extension Features Driver description

-  ==============================================================================
-    [..]          
-      (+) DAC APB clock must be enabled to get write access to DAC
-          registers using HAL_DAC_Init()
-      (+) Configure DAC_OUTx (DAC_OUT1: PA4, DAC_OUT2: PA5) in analog mode.
-      (+) Configure the DAC channel using HAL_DAC_ConfigChannel() function.
-      (+) Enable the DAC channel using HAL_DAC_Start() or HAL_DAC_Start_DMA functions
-
-     *** Polling mode IO operation ***
-     =================================
-     [..]    
-       (+) Start the DAC peripheral using HAL_DAC_Start() 
-       (+) To read the DAC last data output value value, use the HAL_DAC_GetValue() function.
-       (+) Stop the DAC peripheral using HAL_DAC_Stop()
-       
-     *** DMA mode IO operation ***    
-     ==============================
-     [..]    
-       (+) Start the DAC peripheral using HAL_DAC_Start_DMA(), at this stage the user specify the length 
-           of data to be transfered at each end of conversion 
-       (+) At The end of data transfer HAL_DAC_ConvCpltCallbackCh1()or HAL_DAC_ConvCpltCallbackCh2()  
-           function is executed and user can add his own code by customization of function pointer 
-           HAL_DAC_ConvCpltCallbackCh1 or HAL_DAC_ConvCpltCallbackCh2
-       (+) In case of transfer Error, HAL_DAC_ErrorCallbackCh1() function is executed and user can 
-            add his own code by customization of function pointer HAL_DAC_ErrorCallbackCh1
-       (+) Stop the DAC peripheral using HAL_DAC_Stop_DMA()
-                    
-     *** DAC HAL driver macros list ***
-     ============================================= 
-     [..]
-       Below the list of most used macros in DAC HAL driver.
-       
-      (+) __HAL_DAC_ENABLE : Enable the DAC peripheral
-      (+) __HAL_DAC_DISABLE : Disable the DAC peripheral
-      (+) __HAL_DAC_CLEAR_FLAG: Clear the DAC's pending flags
-      (+) __HAL_DAC_GET_FLAG: Get the selected DAC's flag status

-  * @brief   DMA HAL module driver.
-  *    
-  *          This file provides firmware functions to manage the following 
-  *          functionalities of the Direct Memory Access (DMA) peripheral:
-  *           + Initialization and de-initialization functions
-  *           + IO operation functions
-  *           + Peripheral State and errors functions
-  @verbatim     
-  ==============================================================================      
-                        ##### How to use this driver #####
-  ============================================================================== 
-  [..]
-   (#) Enable and configure the peripheral to be connected to the DMA Stream
-       (except for internal SRAM/FLASH memories: no initialization is 
-       necessary) please refer to Reference manual for connection between peripherals
-       and DMA requests . 
-          
-   (#) For a given Stream, program the required configuration through the following parameters:   
-       Transfer Direction, Source and Destination data formats, 
-       Circular, Normal or peripheral flow control mode, Stream Priority level, 
-       Source and Destination Increment mode, FIFO mode and its Threshold (if needed), 
-       Burst mode for Source and/or Destination (if needed) using HAL_DMA_Init() function.
-                     
-     *** Polling mode IO operation ***
-     =================================   
-    [..] 
-          (+) Use HAL_DMA_Start() to start DMA transfer after the configuration of Source 
-              address and destination address and the Length of data to be transferred
-          (+) Use HAL_DMA_PollForTransfer() to poll for the end of current transfer, in this  
-              case a fixed Timeout can be configured by User depending from his application.
-               
-     *** Interrupt mode IO operation ***    
-     =================================== 
-    [..]     
-          (+) Configure the DMA interrupt priority using HAL_NVIC_SetPriority()
-          (+) Enable the DMA IRQ handler using HAL_NVIC_EnableIRQ() 
-          (+) Use HAL_DMA_Start_IT() to start DMA transfer after the configuration of  
-              Source address and destination address and the Length of data to be transferred. In this 
-              case the DMA interrupt is configured 
-          (+) Use HAL_DMA_IRQHandler() called under DMA_IRQHandler() Interrupt subroutine
-          (+) At the end of data transfer HAL_DMA_IRQHandler() function is executed and user can 
-              add his own function by customization of function pointer XferCpltCallback and 
-              XferErrorCallback (i.e a member of DMA handle structure). 
-                
-     (#) Use HAL_DMA_GetState() function to return the DMA state and HAL_DMA_GetError() in case of error 
-         detection.
-         
-     (#) Use HAL_DMA_Abort() function to abort the current transfer
-     
-     -@-   In Memory-to-Memory transfer mode, Circular mode is not allowed.
-    
-     -@-   The FIFO is used mainly to reduce bus usage and to allow data packing/unpacking: it is
-           possible to set different Data Sizes for the Peripheral and the Memory (ie. you can set
-           Half-Word data size for the peripheral to access its data register and set Word data size
-           for the Memory to gain in access time. Each two half words will be packed and written in
-           a single access to a Word in the Memory).
-      
-     -@-   When FIFO is disabled, it is not allowed to configure different Data Sizes for Source
-           and Destination. In this case the Peripheral Data Size will be applied to both Source
-           and Destination.               
-  
-     *** DMA HAL driver macros list ***
-     ============================================= 
-     [..]
-       Below the list of most used macros in DMA HAL driver.
-       
-      (+) __HAL_DMA_ENABLE: Enable the specified DMA Stream.
-      (+) __HAL_DMA_DISABLE: Disable the specified DMA Stream.
-      (+) __HAL_DMA_GET_FS: Return the current DMA Stream FIFO filled level.
-      (+) __HAL_DMA_GET_FLAG: Get the DMA Stream pending flags.
-      (+) __HAL_DMA_CLEAR_FLAG: Clear the DMA Stream pending flags.
-      (+) __HAL_DMA_ENABLE_IT: Enable the specified DMA Stream interrupts.
-      (+) __HAL_DMA_DISABLE_IT: Disable the specified DMA Stream interrupts.
-      (+) __HAL_DMA_GET_IT_SOURCE: Check whether the specified DMA Stream interrupt has occurred or not. 
-     
-     [..] 
-      (@) You can refer to the DMA HAL driver header file for more useful macros

-  * @brief   FLASH HAL module driver.
-  *          This file provides firmware functions to manage the following 
-  *          functionalities of the internal FLASH memory:
-  *           + Program operations functions

-  ==============================================================================
-                        ##### FLASH peripheral features #####
-  ==============================================================================
-           
-  [..] The Flash memory interface manages CPU AHB I-Code and D-Code accesses 
-       to the Flash memory. It implements the erase and program Flash memory operations 
-       and the read and write protection mechanisms.
-      
-  [..] The Flash memory interface accelerates code execution with a system of instruction
-       prefetch and cache lines. 
-
-  [..] The FLASH main features are:
-      (+) Flash memory read operations
-      (+) Flash memory program/erase operations
-      (+) Read / write protections
-      (+) Prefetch on I-Code
-      (+) 64 cache lines of 128 bits on I-Code
-      (+) 8 cache lines of 128 bits on D-Code
-      
-      
-                     ##### How to use this driver #####
-  ==============================================================================
-    [..]                             
-      This driver provides functions and macros to configure and program the FLASH 
-      memory of all STM32F2xx devices.
-    
-      (#) FLASH Memory IO Programming functions: 
-           (++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and 
-                HAL_FLASH_Lock() functions
-           (++) Program functions: byte, half word, word and double word
-           (++) There Two modes of programming :
-            (+++) Polling mode using HAL_FLASH_Program() function
-            (+++) Interrupt mode using HAL_FLASH_Program_IT() function
-    
-      (#) Interrupts and flags management functions : 
-           (++) Handle FLASH interrupts by calling HAL_FLASH_IRQHandler()
-           (++) Wait for last FLASH operation according to its status
-           (++) Get error flag status by calling HAL_SetErrorCode()          
-
-    [..] 
-      In addition to these functions, this driver includes a set of macros allowing
-      to handle the following operations:
-       (+) Set the latency
-       (+) Enable/Disable the prefetch buffer
-       (+) Enable/Disable the Instruction cache and the Data cache
-       (+) Reset the Instruction cache and the Data cache
-       (+) Enable/Disable the FLASH interrupts
-       (+) Monitor the FLASH flags status
-

-  ==============================================================================
-           
-                      ##### How to use this driver #####
-  ==============================================================================
-  [..] This driver provides functions to configure and program the FLASH memory 
-       of all STM32F2xx devices. It includes
-      (#) FLASH Memory Erase functions: 
-           (++) Lock and Unlock the FLASH interface using HAL_FLASH_Unlock() and 
-                HAL_FLASH_Lock() functions
-           (++) Erase function: Erase sector, erase all sectors
-           (++) There is two mode of erase :
-             (+++) Polling Mode using HAL_FLASHEx_Erase()
-             (+++) Interrupt Mode using HAL_FLASHEx_Erase_IT()
-             
-      (#) Option Bytes Programming functions: Use HAL_FLASHEx_OBProgram() to :
-           (++) Set/Reset the write protection
-           (++) Set the Read protection Level
-           (++) Set the BOR level
-           (++) Program the user Option Bytes

-  * @brief   GPIO HAL module driver.
-  *          This file provides firmware functions to manage the following 
-  *          functionalities of the General Purpose Input/Output (GPIO) peripheral:

-                    ##### GPIO Peripheral features #####
-  ==============================================================================         
-  [..] 
-    (+) Each port bit of the general-purpose I/O (GPIO) ports can be individually 
-        configured by software in several modes:
-        (++) Input mode 
-        (++) Analog mode
-        (++) Output mode
-        (++) Alternate function mode
-        (++) External interrupt/event lines
-   
-    (+) During and just after reset, the alternate functions and external interrupt  
-        lines are not active and the I/O ports are configured in input floating mode.
-     
-    (+) All GPIO pins have weak internal pull-up and pull-down resistors, which can be 
-        activated or not.
-
-    (+) In Output or Alternate mode, each IO can be configured on open-drain or push-pull
-        type and the IO speed can be selected depending on the VDD value.
-  
-    (+) The microcontroller IO pins are connected to onboard peripherals/modules through a 
-        multiplexer that allows only one peripheral alternate function (AF) connected 
-       to an IO pin at a time. In this way, there can be no conflict between peripherals 
-       sharing the same IO pin. 
- 
-    (+) All ports have external interrupt/event capability. To use external interrupt 
-        lines, the port must be configured in input mode. All available GPIO pins are 
-        connected to the 16 external interrupt/event lines from EXTI0 to EXTI15.
-   
-    (+) The external interrupt/event controller consists of up to 23 edge detectors 
-        (16 lines are connected to GPIO) for generating event/interrupt requests (each 
-        input line can be independently configured to select the type (interrupt or event) 
-        and the corresponding trigger event (rising or falling or both). Each line can 
-        also be masked independently. 
-  
-                     ##### How to use this driver #####
-  ==============================================================================  
-  [..]             
-    (#) Enable the GPIO AHB clock using the following function: __GPIOx_CLK_ENABLE(). 
-             
-    (#) Configure the GPIO pin(s) using HAL_GPIO_Init().
-        (++) Configure the IO mode using "Mode" member from GPIO_InitTypeDef structure
-        (++) Activate Pull-up, Pull-down resistor using "Pull" member from GPIO_InitTypeDef 
-             structure.
-        (++) In case of Output or alternate function mode selection: the speed is 
-             configured through "Speed" member from GPIO_InitTypeDef structure.
-        (++) In alternate mode is selection, the alternate function connected to the IO
-             is configured through "Alternate" member from GPIO_InitTypeDef structure.
-        (++) Analog mode is required when a pin is to be used as ADC channel 
-             or DAC output.
-        (++) In case of external interrupt/event selection the "Mode" member from 
-             GPIO_InitTypeDef structure select the type (interrupt or event) and 
-             the corresponding trigger event (rising or falling or both).
-   
-    (#) In case of external interrupt/event mode selection, configure NVIC IRQ priority 
-        mapped to the EXTI line using HAL_NVIC_SetPriority() and enable it using
-        HAL_NVIC_EnableIRQ().
-         
-    (#) To get the level of a pin configured in input mode use HAL_GPIO_ReadPin().
-            
-    (#) To set/reset the level of a pin configured in output mode use 
-        HAL_GPIO_WritePin()/HAL_GPIO_TogglePin().
-                 
-    (#) During and just after reset, the alternate functions are not 
-        active and the GPIO pins are configured in input floating mode (except JTAG
-        pins).
-  
-    (#) The LSE oscillator pins OSC32_IN and OSC32_OUT can be used as general purpose 
-        (PC14 and PC15, respectively) when the LSE oscillator is off. The LSE has 
-        priority over the GPIO function.
-  
-    (#) The HSE oscillator pins OSC_IN/OSC_OUT can be used as 
-        general purpose PH0 and PH1, respectively, when the HSE oscillator is off. 
-        The HSE has priority over the GPIO function.

-    The I2C HAL driver can be used as follows:
-
-    (#) Declare a I2C_HandleTypeDef handle structure, for example:
-        I2C_HandleTypeDef  hi2c;
-
-    (#)Initialize the I2C low level resources by implement the HAL_I2C_MspInit() API:
-        (##) Enable the I2Cx interface clock
-        (##) I2C pins configuration
-            (+++) Enable the clock for the I2C GPIOs
-            (+++) Configure I2C pins as alternate function open-drain
-        (##) NVIC configuration if you need to use interrupt process
-            (+++) Configure the I2Cx interrupt priority
-            (+++) Enable the NVIC I2C IRQ Channel
-        (##) DMA Configuration if you need to use DMA process
-            (+++) Declare a DMA_HandleTypeDef handle structure for the transmit or receive stream
-            (+++) Enable the DMAx interface clock using
-            (+++) Configure the DMA handle parameters
-            (+++) Configure the DMA Tx or Rx Stream
-            (+++) Associate the initilalized DMA handle to the hi2c DMA Tx or Rx handle
-            (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx or Rx Stream
-
-    (#) Configure the Communication Speed, Duty cycle, Addressing mode, Own Address1,
-        Dual Addressing mode, Own Address2, General call and Nostretch mode in the hi2c Init structure.
-
-    (#) Initialize the I2C registers by calling the HAL_I2C_Init() API:
-        (+++) These API's configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
-            by calling the customed HAL_I2C_MspInit(&hi2c) API.
-
-    (#) To check if target device is ready for communication, use the function HAL_I2C_IsDeviceReady()
-
-    (#) For I2C IO and IO MEM operations, three mode of operations are available within this driver :

- ===============================================================================
-                  ##### How to use this driver #####
- ===============================================================================
- [..]
-    The I2S HAL driver can be used as follow:
-    
-    (#) Declare a I2S_HandleTypeDef handle structure.
-    (#) Initialize the I2S low level resources by implement the HAL_I2S_MspInit() API:
-        (##) Enable the SPIx interface clock.                      
-        (##) I2S pins configuration:
-            (+++) Enable the clock for the I2S GPIOs.
-            (+++) Configure these I2S pins as alternate function pull-up.
-        (##) NVIC configuration if you need to use interrupt process (HAL_I2S_Transmit_IT()
-             and HAL_I2S_Receive_IT() APIs).
-            (+++) Configure the I2Sx interrupt priority.
-            (+++) Enable the NVIC I2S IRQ handle.
-        (##) DMA Configuration if you need to use DMA process (HAL_I2S_Transmit_DMA()
-             and HAL_I2S_Receive_DMA() APIs:
-            (+++) Declare a DMA handle structure for the Tx/Rx stream.
-            (+++) Enable the DMAx interface clock.
-            (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.                
-            (+++) Configure the DMA Tx/Rx Stream.
-            (+++) Associate the initilalized DMA handle to the I2S DMA Tx/Rx handle.
-            (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the 
-                DMA Tx/Rx Stream.
-  
-   (#) Program the Mode, Standard, Data Format, MCLK Output, Audio frequency and Polarity
-       using HAL_I2S_Init() function.
-
-   -@- The specific I2S interrupts (Transmission complete interrupt, 
-       RXNE interrupt and Error Interrupts) will be managed using the macros
-       __I2S_ENABLE_IT() and __I2S_DISABLE_IT() inside the transmit and receive process.
-   -@- Make sure that either:
-        (+@) I2S PLL is configured or 
-        (+@) External clock source is configured after setting correctly 
-             the define constant EXTERNAL_CLOCK_VALUE in the stm32f2xx_hal_conf.h file. 
-

-    This subsection provides a set of functions allowing to manage the I2S data 
-    transfers.
-
-    (#) There is two mode of transfer:
-       (++) Blocking mode : The communication is performed in the polling mode. 
-            The status of all data processing is returned by the same function 
-            after finishing transfer.  
-       (++) No-Blocking mode : The communication is performed using Interrupts 
-            or DMA. These functions return the status of the transfer startup.
-            The end of the data processing will be indicated through the 
-            dedicated I2S IRQ when using Interrupt mode or the DMA IRQ when 
-            using DMA mode.
-
-    (#) Blocking mode functions are :
-        (++) HAL_I2S_Transmit()
-        (++) HAL_I2S_Receive()
-        
-    (#) No-Blocking mode functions with Interrupt are :
-        (++) HAL_I2S_Transmit_IT()
-        (++) HAL_I2S_Receive_IT()
-
-    (#) No-Blocking mode functions with DMA are :
-        (++) HAL_I2S_Transmit_DMA()
-        (++) HAL_I2S_Receive_DMA()
-
-    (#) A set of Transfer Complete Callbacks are provided in No_Blocking mode:

-                    ##### How to use this driver #####
-  ==============================================================================
-    [..]
-      The PCD HAL driver can be used as follows:
-
-     (#) Declare a PCD_HandleTypeDef handle structure, for example:
-         PCD_HandleTypeDef  hpcd;
-        
-     (#) Fill parameters of Init structure in HCD handle
-  
-     (#) Call HAL_PCD_Init() API to initialize the HCD peripheral (Core, Device core, ...) 
-
-     (#) Initialize the PCD low level resources through the HAL_PCD_MspInit() API:
-         (##) Enable the PCD/USB Low Level interface clock using 
-              (+++) __OTGFS-OTG_CLK_ENABLE()/__OTGHS-OTG_CLK_ENABLE();
-              (+++) __OTGHSULPI_CLK_ENABLE(); (For High Speed Mode)
-           
-         (##) Initialize the related GPIO clocks
-         (##) Configure PCD pin-out
-         (##) Configure PCD NVIC interrupt
-    
-     (#)Associate the Upper USB device stack to the HAL PCD Driver:
-         (##) hpcd.pData = pdev;
-
-     (#)Enable HCD transmission and reception:
-         (##) HAL_PCD_Start();

- ===============================================================================
-     
-    *** PVD configuration ***
-    =========================
-    [..]
-      (+) The PVD is used to monitor the VDD power supply by comparing it to a 
-          threshold selected by the PVD Level (PLS[2:0] bits in the PWR_CR).
-      (+) A PVDO flag is available to indicate if VDD/VDDA is higher or lower 
-          than the PVD threshold. This event is internally connected to the EXTI 
-          line16 and can generate an interrupt if enabled. This is done through
-          __HAL_PVD_EXTI_ENABLE_IT() macro.
-      (+) The PVD is stopped in Standby mode.
-
-    *** WakeUp pin configuration ***
-    ================================
-    [..]
-      (+) WakeUp pin is used to wake up the system from Standby mode. This pin is 
-          forced in input pull-down configuration and is active on rising edges.
-      (+) There is only one WakeUp pin: WakeUp Pin 1 on PA.00.
-
-    *** Low Power modes configuration ***
-    =====================================
-    [..]
-      The devices feature 3 low-power modes:
-      (+) Sleep mode: Cortex-M3 core stopped, peripherals kept running.
-      (+) Stop mode: all clocks are stopped, regulator running, regulator 
-          in low power mode
-      (+) Standby mode: 1.2V domain powered off.
-   
-   *** Sleep mode ***
-   ==================
-    [..]
-      (+) Entry:
-        The Sleep mode is entered by using the HAL_PWR_EnterSLEEPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFI)
-              functions with
-          (++) PWR_SLEEPENTRY_WFI: enter SLEEP mode with WFI instruction
-          (++) PWR_SLEEPENTRY_WFE: enter SLEEP mode with WFE instruction
-      
-      -@@- The Regulator parameter is not used for the STM32F2 family 
-              and is kept as parameter just to maintain compatibility with the 
-              lower power families (STM32L).
-      (+) Exit:
-        Any peripheral interrupt acknowledged by the nested vectored interrupt 
-              controller (NVIC) can wake up the device from Sleep mode.
-
-   *** Stop mode ***
-   =================
-    [..]
-      In Stop mode, all clocks in the 1.2V domain are stopped, the PLL, the HSI,
-      and the HSE RC oscillators are disabled. Internal SRAM and register contents 
-      are preserved.
-      The voltage regulator can be configured either in normal or low-power mode.
-      To minimize the consumption In Stop mode, FLASH can be powered off before 
-      entering the Stop mode using the HAL_PWR_EnableFlashPowerDown() function.
-      It can be switched on again by software after exiting the Stop mode using
-      the HAL_PWR_DisableFlashPowerDown() function. 
-
-      (+) Entry:
-         The Stop mode is entered using the HAL_PWR_EnterSTOPMode(PWR_MAINREGULATOR_ON) 
-             function with:
-          (++) Main regulator ON.
-          (++) Low Power regulator ON.
-      (+) Exit:
-        Any EXTI Line (Internal or External) configured in Interrupt/Event mode.
-
-   *** Standby mode ***
-   ====================
-    [..]
-    (+)
-      The Standby mode allows to achieve the lowest power consumption. It is based 
-      on the Cortex-M3 deep sleep mode, with the voltage regulator disabled. 
-      The 1.2V domain is consequently powered off. The PLL, the HSI oscillator and 
-      the HSE oscillator are also switched off. SRAM and register contents are lost 
-      except for the RTC registers, RTC backup registers, backup SRAM and Standby 
-      circuitry.
-   
-      The voltage regulator is OFF.
-      
-      (++) Entry:
-        (+++) The Standby mode is entered using the HAL_PWR_EnterSTANDBYMode() function.
-      (++) Exit:
-        (+++) WKUP pin rising edge, RTC alarm (Alarm A and Alarm B), RTC wakeup,
-             tamper event, time-stamp event, external reset in NRST pin, IWDG reset.
-
-   *** Auto-wakeup (AWU) from low-power mode ***
-   =============================================
-    [..]
-    
-     (+) The MCU can be woken up from low-power mode by an RTC Alarm event, an RTC 
-      Wakeup event, a tamper event or a time-stamp event, without depending on 
-      an external interrupt (Auto-wakeup mode).
-
-      (+) RTC auto-wakeup (AWU) from the Stop and Standby modes
-       
-        (++) To wake up from the Stop mode with an RTC alarm event, it is necessary to 
-              configure the RTC to generate the RTC alarm using the HAL_RTC_SetAlarm_IT() function.
-
-        (++) To wake up from the Stop mode with an RTC Tamper or time stamp event, it 
-             is necessary to configure the RTC to detect the tamper or time stamp event using the
-                HAL_RTCEx_SetTimeStamp_IT() or HAL_RTCEx_SetTamper_IT() functions.
-                  
-        (++) To wake up from the Stop mode with an RTC WakeUp event, it is necessary to
-              configure the RTC to generate the RTC WakeUp event using the HAL_RTCEx_SetWakeUpTimer_IT() function.

-    *** Main and Backup Regulators configuration ***
-    ================================================
-    [..] 
-      (+) The backup domain includes 4 Kbytes of backup SRAM accessible only from 
-          the CPU, and address in 32-bit, 16-bit or 8-bit mode. Its content is 
-          retained even in Standby or VBAT mode when the low power backup regulator
-          is enabled. It can be considered as an internal EEPROM when VBAT is 
-          always present. You can use the HAL_PWR_EnableBkUpReg() function to 
-          enable the low power backup regulator. 
-
-      (+) When the backup domain is supplied by VDD (analog switch connected to VDD) 
-          the backup SRAM is powered from VDD which replaces the VBAT power supply to 
-          save battery life.
-
-      (+) The backup SRAM is not mass erased by a tamper event. It is read 
-          protected to prevent confidential data, such as cryptographic private 
-          key, from being accessed. The backup SRAM can be erased only through 
-          the Flash interface when a protection level change from level 1 to 
-          level 0 is requested. 
-      -@- Refer to the description of Read protection (RDP) in the Flash 
-          programming manual.
-
-        Refer to the product datasheets for more details.
-
-    *** FLASH Power Down configuration ****
-    =======================================
-    [..] 
-      (+) By setting the FPDS bit in the PWR_CR register by using the 
-          HAL_PWR_EnableFlashPowerDown() function, the Flash memory also enters power 
-          down mode when the device enters Stop mode. When the Flash memory 
-          is in power down mode, an additional startup delay is incurred when 
-          waking up from Stop mode.

-  ==============================================================================
-    [..]  
-      After reset the device is running from Internal High Speed oscillator 
-      (HSI 16MHz) with Flash 0 wait state, Flash prefetch buffer, D-Cache 
-      and I-Cache are disabled, and all peripherals are off except internal
-      SRAM, Flash and JTAG.
-      (+) There is no prescaler on High speed (AHB) and Low speed (APB) busses;
-          all peripherals mapped on these busses are running at HSI speed.
-      (+) The clock for all peripherals is switched off, except the SRAM and FLASH.
-      (+) All GPIOs are in input floating state, except the JTAG pins which
-          are assigned to be used for debug purpose.
-    
-    [..]          
-      Once the device started from reset, the user application has to:        
-      (+) Configure the clock source to be used to drive the System clock
-          (if the application needs higher frequency/performance)
-      (+) Configure the System clock frequency and Flash settings  
-      (+) Configure the AHB and APB busses prescalers
-      (+) Enable the clock for the peripheral(s) to be used
-      (+) Configure the clock source(s) for peripherals which clocks are not
-          derived from the System clock (I2S, RTC, ADC, USB OTG FS/SDIO/RNG)

-    [..]
-      This section provide functions allowing to configure the internal/external oscillators
-      (HSE, HSI, LSE, LSI, PLL, CSS and MCO) and the System busses clocks (SYSCLK, AHB, APB1 
-       and APB2).
-
-    [..] Internal/external clock and PLL configuration
-         (#) HSI (high-speed internal), 16 MHz factory-trimmed RC used directly or through
-             the PLL as System clock source.
-
-         (#) LSI (low-speed internal), 32 KHz low consumption RC used as IWDG and/or RTC
-             clock source.
-
-         (#) HSE (high-speed external), 4 to 26 MHz crystal oscillator used directly or
-             through the PLL as System clock source. Can be used also as RTC clock source.
-
-         (#) LSE (low-speed external), 32 KHz oscillator used as RTC clock source.   
-
-         (#) PLL (clocked by HSI or HSE), featuring two different output clocks:
-           (++) The first output is used to generate the high speed system clock (up to 120 MHz)
-           (++) The second output is used to generate the clock for the USB OTG FS (48 MHz),
-                the random analog generator (<=48 MHz) and the SDIO (<= 48 MHz).
-
-         (#) CSS (Clock security system), once enable using the macro __HAL_RCC_CSS_ENABLE()
-             and if a HSE clock failure occurs(HSE used directly or through PLL as System 
-             clock source), the System clockis automatically switched to HSI and an interrupt
-             is generated if enabled. The interrupt is linked to the Cortex-M3 NMI 
-             (Non-Maskable Interrupt) exception vector.   
-
-         (#) MCO1 (microcontroller clock output), used to output HSI, LSE, HSE or PLL
-             clock (through a configurable prescaler) on PA8 pin.
-
-         (#) MCO2 (microcontroller clock output), used to output HSE, PLL, SYSCLK or PLLI2S
-             clock (through a configurable prescaler) on PC9 pin.
-
-    [..] System, AHB and APB busses clocks configuration  
-         (#) Several clock sources can be used to drive the System clock (SYSCLK): HSI,
-             HSE and PLL.
-             The AHB clock (HCLK) is derived from System clock through configurable 
-             prescaler and used to clock the CPU, memory and peripherals mapped 
-             on AHB bus (DMA, GPIO...). APB1 (PCLK1) and APB2 (PCLK2) clocks are derived 
-             from AHB clock through configurable prescalers and used to clock 
-             the peripherals mapped on these busses. You can use 
-             "HAL_RCC_GetSysClockFreq()" function to retrieve the frequencies of these clocks.  
-
-         -@- All the peripheral clocks are derived from the System clock (SYSCLK) except:
-           (+@) I2S: the I2S clock can be derived either from a specific PLL (PLLI2S) or
-                from an external clock mapped on the I2S_CKIN pin. 
-                You have to use __HAL_RCC_PLLI2S_CONFIG() macro to configure this clock.
-           (+@) RTC: the RTC clock can be derived either from the LSI, LSE or HSE clock
-                divided by 2 to 31. You have to use __HAL_RCC_RTC_CONFIG() and __HAL_RCC_RTC_ENABLE()
-                macros to configure this clock. 
-           (+@) USB OTG FS, SDIO and RTC: USB OTG FS require a frequency equal to 48 MHz
-                to work correctly, while the SDIO require a frequency equal or lower than
-                to 48. This clock is derived of the main PLL through PLLQ divider.
-           (+@) IWDG clock which is always the LSI clock.
-       
-         (#) For the stm32f2xx devices, the maximum
-             frequency of the SYSCLK and HCLK is 120 MHz, PCLK2 60 MHz and PCLK1 30 MHz. 
-             Depending on the device voltage range, the maximum frequency should
-             be adapted accordingly:

-  @verbatim
-  ==============================================================================
-              ##### Backup Domain Operating Condition #####
-  ==============================================================================
-  [..] The real-time clock (RTC), the RTC backup registers, and the backup 
-       SRAM (BKP SRAM) can be powered from the VBAT voltage when the main 
-       VDD supply is powered off.
-       To retain the content of the RTC backup registers, backup SRAM, and supply 
-       the RTC when VDD is turned off, VBAT pin can be connected to an optional 
-       standby voltage supplied by a battery or by another source.
-
-  [..] To allow the RTC to operate even when the main digital supply (VDD) is turned
-       off, the VBAT pin powers the following blocks:
-    (#) The RTC
-    (#) The LSE oscillator
-    (#) The backup SRAM when the low power backup regulator is enabled
-    (#) PC13 to PC15 I/Os, plus PI8 I/O (when available)
-  
-  [..] When the backup domain is supplied by VDD (analog switch connected to VDD),
-       the following functions are available:
-    (#) PC14 and PC15 can be used as either GPIO or LSE pins
-    (#) PC13 can be used as a GPIO or as the RTC_AF1 pin
-    (#) PI8 can be used as a GPIO or as the RTC_AF2 pin
-  
-  [..] When the backup domain is supplied by VBAT (analog switch connected to VBAT 
-       because VDD is not present), the following functions are available:
-    (#) PC14 and PC15 can be used as LSE pins only
-    (#) PC13 can be used as the RTC_AF1 pin 
-    (#) PI8 can be used as the RTC_AF2 pin
-             
-                   ##### Backup Domain Reset #####
-  ==================================================================
-  [..] The backup domain reset sets all RTC registers and the RCC_BDCR register 
-       to their reset values. The BKPSRAM is not affected by this reset. The only
-       way of resetting the BKPSRAM is through the Flash interface by requesting 
-       a protection level change from 1 to 0.
-  [..] A backup domain reset is generated when one of the following events occurs:
-    (#) Software reset, triggered by setting the BDRST bit in the 
-        RCC Backup domain control register (RCC_BDCR). 
-    (#) VDD or VBAT power on, if both supplies have previously been powered off.  
-
-                   ##### Backup Domain Access #####
-  ==================================================================
-  [..] After reset, the backup domain (RTC registers, RTC backup data 
-       registers and backup SRAM) is protected against possible unwanted write 
-       accesses. 
-  [..] To enable access to the RTC Domain and RTC registers, proceed as follows:
-    (+) Enable the Power Controller (PWR) APB1 interface clock using the
-        __PWR_CLK_ENABLE() function.
-    (+) Enable access to RTC domain using the HAL_PWR_EnableBkUpAccess() function.
-    (+) Select the RTC clock source using the __HAL_RCC_RTC_CONFIG() function.
-    (+) Enable RTC Clock using the __HAL_RCC_RTC_ENABLE() function.
-  
-  
-                  ##### How to use this driver #####
-  ==================================================================
-  [..] 
-    (+) Enable the RTC domain access (see description in the section above).
-    (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour 
-        format using the HAL_RTC_Init() function.
-  
-  *** Time and Date configuration ***
-  ===================================
-  [..] 
-    (+) To configure the RTC Calendar (Time and Date) use the HAL_RTC_SetTime() 
-        and HAL_RTC_SetDate() functions.
-    (+) To read the RTC Calendar, use the HAL_RTC_GetTime() and HAL_RTC_GetDate() functions. 
-  
-  *** Alarm configuration ***
-  ===========================
-  [..]
-    (+) To configure the RTC Alarm use the HAL_RTC_SetAlarm() function. 
-        You can also configure the RTC Alarm with interrupt mode using the HAL_RTC_SetAlarm_IT() function.
-    (+) To read the RTC Alarm, use the HAL_RTC_GetAlarm() function.
-  
-                  ##### RTC and low power modes #####
-  ==================================================================
-  [..] The MCU can be woken up from a low power mode by an RTC alternate 
-       function.
-  [..] The RTC alternate functions are the RTC alarms (Alarm A and Alarm B), 
-       RTC wakeup, RTC tamper event detection and RTC time stamp event detection.
-       These RTC alternate functions can wake up the system from the Stop and 
-       Standby low power modes.
-  [..] The system can also wake up from low power modes without depending 
-       on an external interrupt (Auto-wakeup mode), by using the RTC alarm 
-       or the RTC wakeup events.
-  [..] The RTC provides a programmable time base for waking up from the 
-       Stop or Standby mode at regular intervals.
-       Wakeup from STOP and Standby modes is possible only when the RTC clock source
-       is LSE or LSI.

- ===============================================================================
-              ##### Initialization and de-initialization functions #####
- ===============================================================================
-   [..] This section provide functions allowing to initialize and configure the 
-         RTC Prescaler (Synchronous and Asynchronous), RTC Hour format, disable 
-         RTC registers Write protection, enter and exit the RTC initialization mode, 
-         RTC registers synchronization check and reference clock detection enable.
-         (#) The RTC Prescaler is programmed to generate the RTC 1Hz time base. 
-             It is split into 2 programmable prescalers to minimize power consumption.
-             (++) A 7-bit asynchronous prescaler and A 13-bit synchronous prescaler.
-             (++) When both prescalers are used, it is recommended to configure the 
-                 asynchronous prescaler to a high value to minimize consumption.
-         (#) All RTC registers are Write protected. Writing to the RTC registers
-             is enabled by writing a key into the Write Protection register, RTC_WPR.
-         (#) To Configure the RTC Calendar, user application should enter 
-             initialization mode. In this mode, the calendar counter is stopped 
-             and its value can be updated. When the initialization sequence is 
-             complete, the calendar restarts counting after 4 RTCCLK cycles.
-         (#) To read the calendar through the shadow registers after Calendar 
-             initialization, calendar update or after wakeup from low power modes 
-             the software must first clear the RSF flag. The software must then 
-             wait until it is set again before reading the calendar, which means 
-             that the calendar registers have been correctly copied into the 
-             RTC_TR and RTC_DR shadow registers.The HAL_RTC_WaitForSynchro() function 
-             implements the above software sequence (RSF clear and RSF check).

-  * @author  MCD Application Team
-  * @version V1.0.1
-  * @date    25-March-2014
-  * @brief   RTC HAL module driver.
-  *          This file provides firmware functions to manage the following 
-  *          functionalities of the Real Time Clock (RTC) Extension peripheral:
-  *           + RTC Time Stamp functions
-  *           + RTC Tamper functions 
-  *           + RTC Wake-up functions
-  *           + Extension Control functions
-  *           + Extension RTC features functions    
-  *         
-  @verbatim
-  ==============================================================================
-                  ##### How to use this driver #####
-  ==============================================================================
-  [..] 
-    (+) Enable the RTC domain access.
-    (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour 
-        format using the HAL_RTC_Init() function.
-  
-  *** RTC Wakeup configuration ***
-  ================================
-  [..] 
-    (+) To configure the RTC Wakeup Clock source and Counter use the HAL_RTC_SetWakeUpTimer()
-        function. You can also configure the RTC Wakeup timer with interrupt mode 
-        using the HAL_RTC_SetWakeUpTimer_IT() function.
-    (+) To read the RTC WakeUp Counter register, use the HAL_RTC_GetWakeUpTimer() 
-        function.
-  
-  *** TimeStamp configuration ***
-  ===============================
-  [..]
-    (+) Configure the RTC_AFx trigger and enables the RTC TimeStamp using the 
-        HAL_RTC_SetTimeStamp() function. You can also configure the RTC TimeStamp with 
-        interrupt mode using the HAL_RTC_SetTimeStamp_IT() function.
-    (+) To read the RTC TimeStamp Time and Date register, use the HAL_RTC_GetTimeStamp()
-        function.
-    (+) The TIMESTAMP alternate function can be mapped either to RTC_AF1 (PC13)
-        or RTC_AF2 (PI8) depending on the value of TSINSEL bit in 
-        RTC_TAFCR register. The corresponding pin is also selected by HAL_RTC_SetTimeStamp()
-        or HAL_RTC_SetTimeStamp_IT() function.
-  
-  *** Tamper configuration ***
-  ============================
-  [..]
-    (+) Enable the RTC Tamper and Configure the Tamper filter count, trigger Edge 
-        or Level according to the Tamper filter (if equal to 0 Edge else Level) 
-        value, sampling frequency, precharge or discharge and Pull-UP using the 
-        HAL_RTC_SetTamper() function. You can configure RTC Tamper with interrupt 
-        mode using HAL_RTC_SetTamper_IT() function.
-    (+) The TAMPER1 alternate function can be mapped either to RTC_AF1 (PC13)
-        or RTC_AF2 (PI8) depending on the value of TAMP1INSEL bit in 
-        RTC_TAFCR register. The corresponding pin is also selected by HAL_RTC_SetTamper()
-        or HAL_RTC_SetTamper_IT() function.
-  
-  *** Backup Data Registers configuration ***
-  ===========================================
-  [..]
-    (+) To write to the RTC Backup Data registers, use the HAL_RTC_BKUPWrite()
-        function.  
-    (+) To read the RTC Backup Data registers, use the HAL_RTC_BKUPRead()
-        function.

-  ==============================================================================
-                        ##### How to use this driver #####
-  ==============================================================================
-  [..]
-    This driver implements a high level communication layer for read and write from/to 
-    this memory. The needed STM32 hardware resources (SDIO and GPIO) are performed by 
-    the user in HAL_SD_MspInit() function (MSP layer).                             
-    Basically, the MSP layer configuration should be the same as we provide in the 
-    examples.
-    You can easily tailor this configuration according to hardware resources.
-
-  [..]
-    This driver is a generic layered driver for SDIO memories which uses the HAL 
-    SDIO driver functions to interface with SD and uSD cards devices. 
-    It is used as follows:
- 
-    (#)Initialize the SDIO low level resources by implement the HAL_SD_MspInit() API:
-        (##) Enable the SDIO interface clock using __SDIO_CLK_ENABLE(); 
-        (##) SDIO pins configuration for SD card
-            (+++) Enable the clock for the SDIO GPIOs using the functions __GPIOx_CLK_ENABLE();   
-            (+++) Configure these SDIO pins as alternate function pull-up using HAL_GPIO_Init()
-                  and according to your pin assignment;
-        (##) DMA Configuration if you need to use DMA process (HAL_SD_ReadBlocks_DMA()
-             and HAL_SD_WriteBlocks_DMA() APIs).
-            (+++) Enable the DMAx interface clock using __DMAx_CLK_ENABLE(); 
-            (+++) Configure the DMA using the function HAL_DMA_Init() with predeclared and filled. 
-        (##) NVIC configuration if you need to use interrupt process when using DMA transfer.
-            (+++) Configure the SDIO and DMA interrupt priorities using functions
-                  HAL_NVIC_SetPriority(); DMA priority is superior to SDIO's priority
-            (+++) Enable the NVIC DMA and SDIO IRQs using function HAL_NVIC_EnableIRQ()
-            (+++) SDIO interrupts are managed using the macros __HAL_SD_SDIO_ENABLE_IT() 
-                  and __HAL_SD_SDIO_DISABLE_IT() inside the communication process.
-            (+++) SDIO interrupts pending bits are managed using the macros __HAL_SD_SDIO_GET_IT()
-                  and __HAL_SD_SDIO_CLEAR_IT()
-    (#) At this stage, you can perform SD read/write/erase operations after SD card initialization  
-
-         
-  *** SD Card Initialization and configuration ***
-  ================================================    
-  [..]
-    To initialize the SD Card, use the HAL_SD_Init() function.  It Initializes 
-    the SD Card and put it into StandBy State (Ready for data transfer). 
-    This function provide the following operations:
-  
-    (#) Apply the SD Card initialization process at 400KHz and check the SD Card 
-        type (Standard Capacity or High Capacity). You can change or adapt this 
-        frequency by adjusting the "ClockDiv" field. 
-        The SD Card frequency (SDIO_CK) is computed as follows:
-  
-           SDIO_CK = SDIOCLK / (ClockDiv + 2)
-  
-        In initialization mode and according to the SD Card standard, 
-        make sure that the SDIO_CK frequency doesn't exceed 400KHz.
-  
-    (#) Get the SD CID and CSD data. All these information are managed by the SDCardInfo 
-        structure. This structure provide also ready computed SD Card capacity 
-        and Block size.
-        
-        -@- These information are stored in SD handle structure in case of future use.  
-  
-    (#) Configure the SD Card Data transfer frequency. By Default, the card transfer 
-        frequency is set to 24MHz. You can change or adapt this frequency by adjusting 
-        the "ClockDiv" field.
-        The SD Card frequency (SDIO_CK) is computed as follows:
-
-           SDIO_CK = SDIOCLK / (ClockDiv + 2) 
-
-        In transfer mode and according to the SD Card standard, make sure that the 
-        SDIO_CK frequency doesn't exceed 25MHz and 50MHz in High-speed mode switch.
-        To be able to use a frequency higher than 24MHz, you should use the SDIO 
-        peripheral in bypass mode. Refer to the corresponding reference manual 
-        for more details.
-  
-    (#) Select the corresponding SD Card according to the address read with the step 2.
-    
-    (#) Configure the SD Card in wide bus mode: 4-bits data.
-  
-  *** SD Card Read operation ***
-  ==============================
-  [..] 
-    (+) You can read from SD card in polling mode by using function HAL_SD_ReadBlocks(). 
-        This function support only 512-byte block length (the block size should be 
-        chosen as 512 byte).
-        You can choose either one block read operation or multiple block read operation 
-        by adjusting the "NumberOfBlocks" parameter.
-
-    (+) You can read from SD card in DMA mode by using function HAL_SD_ReadBlocks_DMA().
-        This function support only 512-byte block length (the block size should be 
-        chosen as 512 byte).
-        You can choose either one block read operation or multiple block read operation 
-        by adjusting the "NumberOfBlocks" parameter.
-        After this, you have to call the function HAL_SD_CheckReadOperation(), to insure
-        that the read transfer is done correctly in both DMA and SD sides.
-  
-  *** SD Card Write operation ***
-  =============================== 
-  [..] 
-    (+) You can write to SD card in polling mode by using function HAL_SD_WriteBlocks(). 
-        This function support only 512-byte block length (the block size should be 
-        chosen as 512 byte).
-        You can choose either one block read operation or multiple block read operation 
-        by adjusting the "NumberOfBlocks" parameter.
-
-    (+) You can write to SD card in DMA mode by using function HAL_SD_WriteBlocks_DMA().
-        This function support only 512-byte block length (the block size should be 
-        chosen as 512 byte).
-        You can choose either one block read operation or multiple block read operation 
-        by adjusting the "NumberOfBlocks" parameter.
-        After this, you have to call the function HAL_SD_CheckWriteOperation(), to insure
-        that the write transfer is done correctly in both DMA and SD sides.  
-  
-  *** SD card status ***
-  ====================== 
-  [..]
-    (+) At any time, you can check the SD Card status and get the SD card state 
-        by using the HAL_SD_GetStatus() function. This function checks first if the 
-        SD card is still connected and then get the internal SD Card transfer state.     
-    (+) You can also get the SD card SD Status register by using the HAL_SD_SendSDStatus() 
-        function.

-  * @brief   SPI HAL module driver.
-  *

-  *          functionalities of the Serial Peripheral Interface (SPI) peripheral:
-  *           + Initialization and de-initialization functions

-  ==============================================================================
-                        ##### How to use this driver #####
-  ==============================================================================
-    [..]
-      The SPI HAL driver can be used as follows:
-
-      (#) Declare a SPI_HandleTypeDef handle structure, for example:
-          SPI_HandleTypeDef  hspi; 
-
-      (#)Initialize the SPI low level resources by implement the HAL_SPI_MspInit ()API:
-          (##) Enable the SPIx interface clock 
-          (##) SPI pins configuration
-              (+++) Enable the clock for the SPI GPIOs 
-              (+++) Configure these SPI pins as alternate function push-pull
-          (##) NVIC configuration if you need to use interrupt process
-              (+++) Configure the SPIx interrupt priority
-              (+++) Enable the NVIC SPI IRQ handle
-          (##) DMA Configuration if you need to use DMA process
-              (+++) Declare a DMA_HandleTypeDef handle structure for the transmit or receive stream
-              (+++) Enable the DMAx interface clock using 
-              (+++) Configure the DMA handle parameters 
-              (+++) Configure the DMA Tx or Rx Stream
-              (+++) Associate the initilalized hdma_tx handle to the hspi DMA Tx or Rx handle
-              (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx or Rx Stream
-
-      (#) Program the Mode, Direction , Data size, Baudrate Prescaler, NSS 
-          management, Clock polarity and phase, FirstBit and CRC configuration in the hspi Init structure.
-
-      (#) Initialize the SPI registers by calling the HAL_SPI_Init() API:
-          (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
-              by calling the customed HAL_SPI_MspInit(&hspi) API.

-    This subsection provides a set of functions allowing to manage the SPI
-    data transfers.
-
-    [..] The SPI supports master and slave mode :
-
-    (#) There are two mode of transfer:
-       (++) Blocking mode: The communication is performed in polling mode.
-            The HAL status of all data processing is returned by the same function
-            after finishing transfer.
-       (++) No-Blocking mode: The communication is performed using Interrupts
-           or DMA, These API's return the HAL status.
-           The end of the data processing will be indicated through the 
-           dedicated SPI IRQ when using Interrupt mode or the DMA IRQ when 
-           using DMA mode.
-           The HAL_SPI_TxCpltCallback(), HAL_SPI_RxCpltCallback() and HAL_SPI_TxRxCpltCallback() user callbacks 
-           will be executed respectivelly at the end of the transmit or Receive process
-           The HAL_SPI_ErrorCallback()user callback will be executed when a communication error is detected
-
-    (#) Blocking mode API's are :
-        (++) HAL_SPI_Transmit()in 1Line (simplex) and 2Lines (full duplex) mode
-        (++) HAL_SPI_Receive() in 1Line (simplex) and 2Lines (full duplex) mode
-        (++) HAL_SPI_TransmitReceive() in full duplex mode
-
-    (#) Non-Blocking mode API's with Interrupt are :
-        (++) HAL_SPI_Transmit_IT()in 1Line (simplex) and 2Lines (full duplex) mode
-        (++) HAL_SPI_Receive_IT() in 1Line (simplex) and 2Lines (full duplex) mode
-        (++) HAL_SPI_TransmitReceive_IT()in full duplex mode
-        (++) HAL_SPI_IRQHandler()
-
-    (#) No-Blocking mode functions with DMA are :
-        (++) HAL_SPI_Transmit_DMA()in 1Line (simplex) and 2Lines (full duplex) mode
-        (++) HAL_SPI_Receive_DMA() in 1Line (simplex) and 2Lines (full duplex) mode
-        (++) HAL_SPI_TransmitReceie_DMA() in full duplex mode

-                      ##### TIMER Generic features #####
-  ==============================================================================
-  [..] The Timer features include: 
-       (#) 16-bit up, down, up/down auto-reload counter.
-       (#) 16-bit programmable prescaler allowing dividing (also on the fly) the 
-           counter clock frequency either by any factor between 1 and 65536.
-       (#) Up to 4 independent channels for:
-           (++) Input Capture
-           (++) Output Compare
-           (++) PWM generation (Edge and Center-aligned Mode)
-           (++) One-pulse mode output               
-   
-                        ##### How to use this driver #####
-  ==============================================================================
-    [..]
-     (#) Initialize the TIM low level resources by implementing the following functions 
-         depending from feature used :
-           (++) Time Base : HAL_TIM_Base_MspInit() 
-           (++) Input Capture : HAL_TIM_IC_MspInit()
-           (++) Output Compare : HAL_TIM_OC_MspInit()
-           (++) PWM generation : HAL_TIM_PWM_MspInit()
-           (++) One-pulse mode output : HAL_TIM_OnePulse_MspInit()
-           (++) Encoder mode output : HAL_TIM_Encoder_MspInit()
-           
-     (#) Initialize the TIM low level resources :
-        (##) Enable the TIM interface clock using __TIMx_CLK_ENABLE(); 
-        (##) TIM pins configuration
-            (+++) Enable the clock for the TIM GPIOs using the following function:
-                 __GPIOx_CLK_ENABLE();   
-            (+++) Configure these TIM pins in Alternate function mode using HAL_GPIO_Init();  
-
-     (#) The external Clock can be configured, if needed (the default clock is the 
-         internal clock from the APBx), using the following function:
-         HAL_TIM_ConfigClockSource, the clock configuration should be done before 
-         any start function.
-  
-     (#) Configure the TIM in the desired functioning mode using one of the 
-         initialization function of this driver:
-         (++) HAL_TIM_Base_Init: to use the Timer to generate a simple time base
-         (++) HAL_TIM_OC_Init and HAL_TIM_OC_ConfigChannel: to use the Timer to generate an 
-              Output Compare signal.
-         (++) HAL_TIM_PWM_Init and HAL_TIM_PWM_ConfigChannel: to use the Timer to generate a 
-              PWM signal.
-         (++) HAL_TIM_IC_Init and HAL_TIM_IC_ConfigChannel: to use the Timer to measure an 
-              external signal.
-         (++) HAL_TIM_OnePulse_Init and HAL_TIM_OnePulse_ConfigChannel: to use the Timer 
-              in One Pulse Mode.
-         (++) HAL_TIM_Encoder_Init: to use the Timer Encoder Interface.
-         
-     (#) Activate the TIM peripheral using one of the start functions depending from the feature used: 
-           (++) Time Base : HAL_TIM_Base_Start(), HAL_TIM_Base_Start_DMA(), HAL_TIM_Base_Start_IT()
-           (++) Input Capture :  HAL_TIM_IC_Start(), HAL_TIM_IC_Start_DMA(), HAL_TIM_IC_Start_IT()
-           (++) Output Compare : HAL_TIM_OC_Start(), HAL_TIM_OC_Start_DMA(), HAL_TIM_OC_Start_IT()
-           (++) PWM generation : HAL_TIM_PWM_Start(), HAL_TIM_PWM_Start_DMA(), HAL_TIM_PWM_Start_IT()
-           (++) One-pulse mode output : HAL_TIM_OnePulse_Start(), HAL_TIM_OnePulse_Start_IT()
-           (++) Encoder mode output : HAL_TIM_Encoder_Start(), HAL_TIM_Encoder_Start_DMA(), HAL_TIM_Encoder_Start_IT().
-
-     (#) The DMA Burst is managed with the two following functions:
-         HAL_TIM_DMABurst_WriteStart()
-         HAL_TIM_DMABurst_ReadStart()

-  * @brief   TIM HAL module driver.
-  *          This file provides firmware functions to manage the following 
-  *          functionalities of the Timer extension peripheral:
-  *           + Time Hall Sensor Interface Initialization
-  *           + Time Hall Sensor Interface Start

-  ==============================================================================
-                      ##### TIMER Extended features #####
-  ==============================================================================
-  [..] 
-    The Timer Extension features include: 
-    (#) Complementary outputs with programmable dead-time for :
-        (++) Input Capture
-        (++) Output Compare
-        (++) PWM generation (Edge and Center-aligned Mode)
-        (++) One-pulse mode output
-    (#) Synchronization circuit to control the timer with external signals and to 
-        interconnect several timers together.
-    (#) Break input to put the timer output signals in reset state or in a known state.
-    (#) Supports incremental (quadrature) encoder and hall-sensor circuitry for 
-        positioning purposes                
-   
-                        ##### How to use this driver #####
-  ==============================================================================
-  [..]
-     (#) Initialize the TIM low level resources by implementing the following functions 
-         depending from feature used :
-           (++) Complementary Output Compare : HAL_TIM_OC_MspInit()
-           (++) Complementary PWM generation : HAL_TIM_PWM_MspInit()
-           (++) Complementary One-pulse mode output : HAL_TIM_OnePulse_MspInit()
-           (++) Hall Sensor output : HAL_TIM_HallSensor_MspInit()
-           
-     (#) Initialize the TIM low level resources :
-        (##) Enable the TIM interface clock using __TIMx_CLK_ENABLE(); 
-        (##) TIM pins configuration
-            (+++) Enable the clock for the TIM GPIOs using the following function:
-                 __GPIOx_CLK_ENABLE();   
-            (+++) Configure these TIM pins in Alternate function mode using HAL_GPIO_Init();  
-
-     (#) The external Clock can be configured, if needed (the default clock is the 
-         internal clock from the APBx), using the following function:
-         HAL_TIM_ConfigClockSource, the clock configuration should be done before 
-         any start function.
-  
-    (#) Configure the TIM in the desired functioning mode using one of the 
-        initialization function of this driver:
-        (++) HAL_TIMEx_HallSensor_Init and HAL_TIMEx_ConfigCommutationEvent: to use the 
-             Timer Hall Sensor Interface and the commutation event with the corresponding 
-             Interrupt and DMA request if needed (Note that One Timer is used to interface 
-             with the Hall sensor Interface and another Timer should be used to use 
-             the commutation event).
-
-    (#) Activate the TIM peripheral using one of the start functions: 
-           (++) Complementary Output Compare : HAL_TIMEx_OCN_Start(), HAL_TIMEx_OCN_Start_DMA(), HAL_TIMEx_OC_Start_IT()
-           (++) Complementary PWM generation : HAL_TIMEx_PWMN_Start(), HAL_TIMEx_PWMN_Start_DMA(), HAL_TIMEx_PWMN_Start_IT()
-           (++) Complementary One-pulse mode output : HAL_TIMEx_OnePulseN_Start(), HAL_TIMEx_OnePulseN_Start_IT()
-           (++) Hall Sensor output : HAL_TIMEx_HallSensor_Start(), HAL_TIMEx_HallSensor_Start_DMA(), HAL_TIMEx_HallSensor_Start_IT().

-  ==============================================================================
-                        ##### How to use this driver #####
-  ==============================================================================
-  [..]
-    The UART HAL driver can be used as follows:
-    
-    (#) Declare a UART_HandleTypeDef handle structure.
-  
-    (#) Initialize the UART low level resources by implement the HAL_UART_MspInit() API:
-        (##) Enable the USARTx interface clock.
-        (##) UART pins configuration:
-            (+++) Enable the clock for the UART GPIOs.
-            (+++) Configure these UART pins as alternate function pull-up.
-        (##) NVIC configuration if you need to use interrupt process (HAL_UART_Transmit_IT()
-             and HAL_UART_Receive_IT() APIs):
-            (+++) Configure the USARTx interrupt priority.
-            (+++) Enable the NVIC USART IRQ handle.
-        (##) DMA Configuration if you need to use DMA process (HAL_UART_Transmit_DMA()
-             and HAL_UART_Receive_DMA() APIs):
-            (+++) Declare a DMA handle structure for the Tx/Rx stream.
-            (+++) Enable the DMAx interface clock.
-            (+++) Configure the declared DMA handle structure with the required 
-                  Tx/Rx parameters.                
-            (+++) Configure the DMA Tx/Rx Stream.
-            (+++) Associate the initialized DMA handle to the UART DMA Tx/Rx handle.
-            (+++) Configure the priority and enable the NVIC for the transfer complete 
-                  interrupt on the DMA Tx/Rx Stream.
-
-    (#) Program the Baud Rate, Word Length, Stop Bit, Parity, Hardware 
-        flow control and Mode(Receiver/Transmitter) in the huart Init structure.
-
-    (#) For the UART asynchronous mode, initialize the UART registers by calling
-        the HAL_UART_Init() API.
-    
-    (#) For the UART Half duplex mode, initialize the UART registers by calling 
-        the HAL_HalfDuplex_Init() API.
-    
-    (#) For the LIN mode, initialize the UART registers by calling the HAL_LIN_Init() API.
-    
-    (#) For the Multi-Processor mode, initialize the UART registers by calling 
-        the HAL_MultiProcessor_Init() API.
-        
-        -@- The specific UART interrupts (Transmission complete interrupt, 
-            RXNE interrupt and Error Interrupts) will be managed using the macros
-            __HAL_UART_ENABLE_IT() and __HAL_UART_DISABLE_IT() inside the transmit 
-            and receive process.
-          
-        -@- These API's(HAL_UART_Init() and HAL_HalfDuplex_Init()) configures also the 
-            low level Hardware GPIO, CLOCK, CORTEX...etc) by calling the customed 
-            HAL_UART_MspInit() API.
-          
-    (#) Three mode of operations are available within this driver :     
-

-    This subsection provides a set of functions allowing to initialize the USARTx or the UARTy 
-    in asynchronous mode.
-      (+) For the asynchronous mode only these parameters can be configured: 
-        (++) Baud Rate
-        (++) Word Length 
-        (++) Stop Bit
-        (++) Parity: If the parity is enabled, then the MSB bit of the data written
-             in the data register is transmitted but is changed by the parity bit.
-             Depending on the frame length defined by the M bit (8-bits or 9-bits),
-             the possible UART frame formats are as listed in the following table:

-    This subsection provides a set of functions allowing to manage the UART asynchronous
-    and Half duplex data transfers.
-
-    (#) There are two modes of transfer:
-       (++) Blocking mode: The communication is performed in polling mode. 
-            The HAL status of all data processing is returned by the same function 
-            after finishing transfer.  
-       (++) Non-Blocking mode: The communication is performed using Interrupts 
-            or DMA, these APIs return the HAL status.
-            The end of the data processing will be indicated through the 
-            dedicated UART IRQ when using Interrupt mode or the DMA IRQ when 
-            using DMA mode.
-            The HAL_UART_TxCpltCallback(), HAL_UART_RxCpltCallback() user callbacks 
-            will be executed respectivelly at the end of the transmit or receive process.
-            The HAL_UART_ErrorCallback() user callback will be executed when 
-            a communication error is detected.
-
-    (#) Blocking mode API's are:
-        (++) HAL_UART_Transmit()
-        (++) HAL_UART_Receive() 
-        
-    (#) Non-Blocking mode API's with Interrupt are:
-        (++) HAL_UART_Transmit_IT()
-        (++) HAL_UART_Receive_IT()
-        (++) HAL_UART_IRQHandler()
-
-    (#) No-Blocking mode functions with DMA are:
-        (++) HAL_UART_Transmit_DMA()
-        (++) HAL_UART_Receive_DMA()
-
-    (#) A set of Transfer Complete Callbacks are provided in Non-Blocking mode:
-        (++) HAL_UART_TxCpltCallback()
-        (++) HAL_UART_RxCpltCallback()
-        (++) HAL_UART_ErrorCallback()
-
-    [..] 
-      (@) In the Half duplex communication, it is forbidden to run the transmit 
-          and receive process in parallel, the UART state HAL_UART_STATE_BUSY_TX_RX 
-          can't be useful.

-  ==============================================================================
-                       ##### SDMMC peripheral features #####
-  ==============================================================================        
-    [..] The SD/SDIO MMC card host interface (SDIO) provides an interface between the APB2
-         peripheral bus and MultiMedia cards (MMCs), SD memory cards, SDIO cards and CE-ATA
-         devices.
-
-    [..] The MultiMedia Card system specifications are available through the MultiMedia Card
-         Association website at www.mmca.org, published by the MMCA technical committee.
-         SD memory card and SD I/O card system specifications are available through the SD card
-         Association website at www.sdcard.org.
-         CE-ATA system specifications are available through the CE-ATA work group web site at
-         www.ce-ata.org.
-    
-    [..] The SDIO features include the following:
-         (+) Full compliance with MultiMedia Card System Specification Version 4.2. Card support
-             for three different databus modes: 1-bit (default), 4-bit and 8-bit
-         (+) Full compatibility with previous versions of MultiMedia Cards (forward compatibility)
-         (+) Full compliance with SD Memory Card Specifications Version 2.0
-         (+) Full compliance with SD I/O Card Specification Version 2.0: card support for two
-             different data bus modes: 1-bit (default) and 4-bit
-         (+) Full support of the CE-ATA features (full compliance with CE-ATA digital protocol
-             Rev1.1)
-         (+) Data transfer up to 48 MHz for the 8 bit mode
-         (+) Data and command output enable signals to control external bidirectional drivers.
-                 
-   
-                           ##### How to use this driver #####
-  ==============================================================================
-    [..]
-      This driver is a considered as a driver of service for external devices drivers 
-      that interfaces with the SDIO peripheral.
-      According to the device used (SD card/ MMC card / SDIO card ...), a set of APIs 
-      is used in the device's driver to perform SDIO operations and functionalities.
-   
-      This driver is almost transparent for the final user, it is only used to implement other
-      functionalities of the external device.
-   
-    [..]
-      (+) The SDIO clock (SDIOCLK = 48 MHz) is coming from a specific output of PLL 
-          (PLL48CLK). Before start working with SDIO peripheral make sure that the
-          PLL is well configured.
-          The SDIO peripheral uses two clock signals:
-          (++) SDIO adapter clock (SDIOCLK = 48 MHz)
-          (++) APB2 bus clock (PCLK2)
-       
-          -@@- PCLK2 and SDIO_CK clock frequencies must respect the following condition:
-               Frequency(PCLK2) >= (3 / 8 x Frequency(SDIO_CK))
-  
-      (+) Enable/Disable peripheral clock using RCC peripheral macros related to SDIO
-          peripheral.
-
-      (+) Enable the Power ON State using the HAL_SDIO_PowerState_ON(hsdio) 
-          function and disable it using the function HAL_SDIO_PowerState_OFF(hsdio).
-                
-      (+) Enable/Disable the clock using the __SDIO_ENABLE()/__SDIO_DISABLE() macros.
-  
-      (+) Enable/Disable the peripheral interrupts using the macros __SDIO_ENABLE_IT(hsdio, IT) 
-          and __SDIO_DISABLE_IT(hsdio, IT) if you need to use interrupt mode. 
-  
-      (+) When using the DMA mode 
-          (++) Configure the DMA in the MSP layer of the external device
-          (++) Active the needed channel Request 
-          (++) Enable the DMA using __SDIO_DMA_ENABLE() macro or Disable it using the macro
-               __SDIO_DMA_DISABLE().
-  
-      (+) To control the CPSM (Command Path State Machine) and send 
-          commands to the card use the HAL_SDIO_SendCommand(), 
-          HAL_SDIO_GetCommandResponse() and HAL_SDIO_GetResponse() functions. First, user has
-          to fill the command structure (pointer to SDIO_CmdInitTypeDef) according 
-          to the selected command to be sent.
-          The parameters that should be filled are:
-           (++) Command Argument
-           (++) Command Index
-           (++) Command Response type
-           (++) Command Wait
-           (++) CPSM Status (Enable or Disable).
-  
-          -@@- To check if the command is well received, read the SDIO_CMDRESP
-              register using the HAL_SDIO_GetCommandResponse().
-              The SDIO responses registers (SDIO_RESP1 to SDIO_RESP2), use the
-              HAL_SDIO_GetResponse() function.
-  
-      (+) To control the DPSM (Data Path State Machine) and send/receive 
-           data to/from the card use the HAL_SDIO_DataConfig(), HAL_SDIO_GetDataCounter(), 
-          HAL_SDIO_ReadFIFO(), HAL_SDIO_WriteFIFO() and HAL_SDIO_GetFIFOCount() functions.
