This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.

|
There is a minor functional change with this patch, that the GPIO are now
configured in fast mode, whereas they were in high speed mode before. But
the SDIO should still work because SD CK frequency is at most 25MHz.
|
|
This follows the pattern of other peripherals (I2C, SPI) to specify the
pins using pin objects instead of a pair of GPIO port and pin number. It
makes it easier to customise the UART pins for a particular board.
|
|
changes include:
* use single GPIO.BSRR instead of BSRRH and BSRRL
* change HSE_STARTUP_TIMEOUT to 100 ms
* define LSE_STARTUP_TIMEOUT to 5 s

As part of this patch the MICROPY_HW_LED_OTYPE setting is removed because
it is now unused (all boards anyway had this as OUTPUT_PP).
|
|
This allows PYBv3 to use PWM for LED(1) and LED(2).
|
|
To allow to reuse stmhal/diskio for ports which don't have flash but have
other storage devices.
|
|
Previously, SPI was configured by a board defining MICROPY_HW_ENABLE_SPIx
to 0 or 1. Now, the board should define MICROPY_HW_SPIx_SCK, MISO, MOSI
and NSS. This makes it the same as how I2C is configured.

This needs to land afte #1407 lands, since #1407 is where
the CMSIS_MCU was defined.
|
|
This causes unnecessary constants to no longer be generated.
Some constants (like UART_BRR) are different between the F4 and F7
|
|
|
|
Now all stmhal-based boards can name their peripherals (if they want) to
any string.
|
|
|
|
Each board now needs an mpconfigboard.mk file which defines AF_FILE and
LD_FILE.
Also moved stm32f405.ld to boards/ directory to keep things organised.

|
Most boards (except the pyboard) don't have a 32kHz crystal so they
should use the LSI for the RTC.
|
|
|
|
Since all currently supported boards use pin A9 for this function, the
value of the macro MICROPY_HW_USB_VBUS_DETECT_PIN is not actually used,
just the fact that it is defined.
Addresses issue #1048.

Pulled in and modified work done by mux/iabdalkader on cc3k driver, from
iabdalkader-cc3k-update branch. That branch was terribly messy and had
too many conflicts to merge neatly.

This patch updates ST's HAL to the latest version, V1.3.0, dated 19 June
2014. Files were copied verbatim from the ST package. Only change was
to suppress compiler warning of unused variables in 4 places.
A lot of the changes from ST are cosmetic: comments and white space.
Some small code changes here and there, and addition of F411 header.
Main code change is how SysTick interrupt is set: it now has a
configuration variable to set the priority, so we no longer need to work
around this (originall in system_stm32f4xx.c).

This renames MICROPY_HW_HAS_WLAN to MICROPY_HW_ENABLE_CC3K (since it's a
driver, not a board feature) and wraps all CC3000 code in this #if.
It's disabled for all boards.
|
|
|
|
The HAL handles for the I2C/SPI objects are rather large, so we don't
want to unnecessarily include them.
|
|
All board config macros now begin with MICROPY_HW_.
Renamed PYBv10 to PYBV10, since macros should be all uppercase.
Made SDCARD_DETECT configurable in mpconfigport.h, so that the SD
detect pin can be easily configured.
