2021-02-09esp8266/modules: Fix fs_corrupted() to use start_sec not START_SEC.Damien George
START_SEC was changed in e0905e85a7ad2961aa9192f6130565860e531ad3. Also, update the error message to mention how to format the partition at the REPL, and make the total message shorter to save a bit of flash. Signed-off-by: Damien George <damien@micropython.org>
2021-02-05py/gc: Change include of stdint.h to stddef.h.Damien George
No std-int types are used in gc.h, but size_t is which needs stddef.h. Signed-off-by: Damien George <damien@micropython.org>
2021-02-04ports: Remove def of MP_PLAT_PRINT_STRN if it's the same as the default.Damien George
To simplify config, there's no need to specify MP_PLAT_PRINT_STRN if it's the same as the default definition in py/mpconfig.h. Signed-off-by: Damien George <damien@micropython.org>
2021-02-04py/gc: Don't include mpconfig.h and misc.h in gc.h.Xiang Xiao
Because gc.h doesn't reference any symbol from these header files. Signed-off-by: Xiang Xiao <xiaoxiang@xiaomi.com>
2021-01-30esp8266/modules/neopixel.py: Add timing param to NeoPixel constructor.Christopher Tse
This matches the esp32 port.
2020-11-18esp32,esp8266: Remove "FAT" from warning message in inisetup.py.robert
Because FAT is not any more the only filesystem used.
2020-10-29esp8266/mpconfigport.h: Seed the urandom module on import.robert
For seeding, the hardware RNG of the esp8266 is used.
2020-10-01extmod/utime_mphal: Add generic utime.time_ns() function.Damien George
It requires mp_hal_time_ns() to be provided by a port. This function allows very accurate absolute timestamps. Enabled on unix, windows, stm32, esp8266 and esp32. Signed-off-by: Damien George <damien@micropython.org>
2020-10-01ports: Support legacy soft I2C/SPI construction via id=-1 arg.Damien George
With a warning that this way of constructing software I2C/SPI is deprecated. The check and warning will be removed in a future release. This should help existing code to migrate to the new SoftI2C/SoftSPI types. Signed-off-by: Damien George <damien@micropython.org>
2020-10-01ports: Add SoftI2C and SoftSPI to machine module where appropriate.Damien George
Previous commits removed the ability for one I2C/SPI constructor to construct both software- or hardware-based peripheral instances. Such construction is now split to explicit soft and non-soft types. This commit makes both types available in all ports that previously could create both software and hardware peripherals: machine.I2C and machine.SPI construct hardware instances, while machine.SoftI2C and machine.SoftSPI create software instances. This is a breaking change for use of software-based I2C and SPI. Code that constructed I2C/SPI peripherals in the following way will need to be changed: machine.I2C(-1, ...) -> machine.SoftI2C(...) machine.I2C(scl=scl, sda=sda) -> machine.SoftI2C(scl=scl, sda=sda) machine.SPI(-1, ...) -> machine.SoftSPI(...) machine.SPI(sck=sck, mosi=mosi, miso=miso) -> machine.SoftSPI(sck=sck, mosi=mosi, miso=miso) Code which uses machine.I2C and machine.SPI classes to access hardware peripherals does not need to change. Signed-off-by: Damien George <damien@micropython.org>
2020-10-01extmod/machine_spi: Remove "id" arg in SoftSPI constructor.Damien George
The SoftSPI constructor is now used soley to create SoftSPI instances, it can no longer delegate to create a hardware-based SPI instance. Signed-off-by: Damien George <damien@micropython.org>
2020-10-01extmod/machine_i2c: Rename type to SoftI2C and add custom print method.Damien George
Also rename machine_i2c_type to mp_machine_soft_i2c_type. These changes make it clear that it's a soft-I2C implementation, and match SoftSPI. Signed-off-by: Damien George <damien@micropython.org>
2020-09-18all: Rename absolute time-based functions to include "epoch".Damien George
For time-based functions that work with absolute time there is the need for an Epoch, to set the zero-point at which the absolute time starts counting. Such functions include time.time() and filesystem stat return values. And different ports may use a different Epoch. To make it clearer what functions use the Epoch (whatever it may be), and make the ports more consistent with their use of the Epoch, this commit renames all Epoch related functions to include the word "epoch" in their name (and remove references to "2000"). Along with this rename, the following things have changed: - mp_hal_time_ns() is now specified to return the number of nanoseconds since the Epoch, rather than since 1970 (but since this is an internal function it doesn't change anything for the user). - littlefs timestamps on the esp8266 have been fixed (they were previously off by 30 years in nanoseconds). Otherwise, there is no functional change made by this commit. Signed-off-by: Damien George <damien@micropython.org>
2020-09-18ports: Add utime.gmtime() function.Damien George
To portably get the Epoch. This is simply aliased to localtime() on ports that are not timezone aware. Signed-off-by: Damien George <damien@micropython.org>
2020-09-18esp8266: Remove release-specific manifest, disable osdebug by default.Damien George
This commit removes release-specific builds for the esp8266 and makes the normal build of the GENERIC board more like the release build. This makes esp8266 like all the other ports, for which there is no difference between a daily build and a release build, making things less confusing. Release builds were previously defined by UART_OS=-1 (disable OS messages) and using manifest_release.py to include more frozen modules. The changes in this commit are: - Remove manifest_release.py. - Add existing modules from manifest_release.py (except example code) to the GENERIC board's manifest.py file. - Change UART_OS default to -1 to disable OS messages by default. Signed-off-by: Damien George <damien@micropython.org>
2020-08-22py/mphal.h: Introduce mp_hal_time_ns and implement on various ports.Damien George
This should return a 64-bit value being the number of nanoseconds since 1970/1/1. Signed-off-by: Damien George <damien@micropython.org>
2020-05-27esp8266/esppwm: Fix PWM glitch when setting duty on different channel.Olivier Ortigues
The PWM driver uses a double buffer for the PWM timing array, one in current use and the other one to update when changing duty parameters. The issue was that once the duty parameters were changed the updated buffer was applied immediately without synchronising to the start of the PWM period. By moving the buffer toggling/swapping to the interrupt when the cycle is done there are no more glitches.
2020-05-14esp8266/boards: Allow configuring btree/FAT/LFS2 support when building.Rafael Römhild
Prior to e0905e85a7ad2961aa9192f6130565860e531ad3 it was possible to disable btree support on build. This patch allows to configure btree support on make again and also the two new introduced options for FAT and LFS2 filesystems.
2020-05-08esp8266/uart: Move a few functions from iRAM to iROM.Damien George
They call functions in iROM so do not need to be in iRAM.
2020-05-08esp8266/esp_mphal: Move most functions in esp_mphal.c from iRAM to iROM.Damien George
The ones that are moved out of iRAM should not need to be there, because either they call functions in iROM (eg mp_hal_stdout_tx_str), or they are only ever called from a function in iROM and not from an interrupt (eg ets_esf_free_bufs). This frees up about 800 bytes of iRAM.
2020-05-08esp8266/boards: Move py/pairheap.c code from iRAM to iROM.Damien George
It doesn't need to be in iRAM.
2020-05-08esp8266: Clean up Pin intr handler by moving all code to machine_pin.c.Damien George
The macro MP_FASTCODE is used to explicitly place required functions in iRAM, instead of needing a separate .c file.
2020-04-30esp8266/mpconfigport.h: Add definitions for BEGIN/END_ATOMIC_SECTION.Damien George
These are needed to ensure correct operation of the MicroPython scheduler.
2020-04-30esp8266/machine_pin: Move pin_intr_handler to iRAM, de-support hard IRQ.Damien George
GPIO interrupts can occur when the flash ROM cache is in use and so the GPIO interrupt handler must be in iRAM. This commit moves the handler to iRAM, and also moves mp_sched_schedule to iRAM which is called by pin_intr_handler. As part of this fix the Pin class can no longer support hard=True in the Pin.irq() method, because the VM and runtime are too big to put in iRAM. Fixes #5714.
2020-04-27py/stream: Remove mp_stream_errno and use system errno instead.Damien George
This change is made for two reasons: 1. A 3rd-party library (eg berkeley-db-1.xx, axtls) may use the system provided errno for certain errors, and yet MicroPython stream objects that it calls will be using the internal mp_stream_errno. So if the library returns an error it is not known whether the corresponding errno code is stored in the system errno or mp_stream_errno. Using the system errno in all cases (eg in the mp_stream_posix_XXX wrappers) fixes this ambiguity. 2. For systems that have threading the system-provided errno should always be used because the errno value is thread-local. For systems that do not have an errno, the new lib/embed/__errno.c file is provided.
2020-04-23all: Format code to add space after C++-style comment start.stijn
Note: the uncrustify configuration is explicitly set to 'add' instead of 'force' in order not to alter the comments which use extra spaces after // as a means of indenting text for clarity.
2020-04-23all: Remove commented-out include statements.stijn
2020-04-05ports: Enable error text compression for various ports, but not all.Jim Mussared
Enabled on: bare-arm, minimal, unix coverage/dev/minimal, stm32, esp32, esp8266, cc3200, teensy, qemu-arm, nrf. Not enabled on others to be able to test the code when the feature is disabled (the default case).

2020-04-04esp8266/makeimg.py: Print out info about RAM segments when building fw.Damien George
2020-04-04esp8266: Change from FAT to littlefs v2 as default filesystem.Damien George
This commit changes the esp8266 boards to use littlefs v2 as the filesystem, rather than FAT. Since the esp8266 doesn't expose the filesystem to the PC over USB there's no strong reason to keep it as FAT. Littlefs is smaller in code size, is more efficient in use of flash to store data, is resilient over power failure, and using it saves about 4k of heap RAM, which can now be used for other things. This is a backwards incompatible change because all existing esp8266 boards will need to update their filesystem after installing new firmware (eg backup old files, install firmware, restore files to new filesystem). As part of this commit the memory layout of the default board (GENERIC) has changed. It now allocates all 1M of memory-mapped flash to the firmware, so the filesystem area starts at the 2M point. This is done to allow more frozen bytecode to be stored in the 1M of memory-mapped flash. This requires an esp8266 module with 2M or more of flash to work, so a new board called GENERIC_1M is added which has the old memory-mapping (but still changed to use littlefs for the filesystem). In summary there are now 3 esp8266 board definitions: - GENERIC_512K: for 512k modules, doesn't have a filesystem. - GENERIC_1M: for 1M modules, 572k for firmware+frozen code, 396k for filesystem (littlefs). - GENERIC: for 2M (or greater) modules, 968k for firmware+frozen code, 1M+ for filesystem (littlefs), FAT driver also included in firmware for use on, eg, external SD cards.
2020-03-28all: Remove spaces inside and around parenthesis.Damien George
Using new options enabled in the uncrustify configuration.
2020-03-26esp8266: Enable and freeze uasyncio.Damien George
Only included in GENERIC build.
2020-03-25ports: Add lib/libm/roundf.c to bare-metal Makefile's.Zoltán Vörös
This function is not used by the core but having it as part of the build allows it to be used by user C modules, or board extensions. The linker won't include it in the final firmware if it remains unused.
2020-03-25esp8266/modnetwork: Add support for wlan.ifconfig('dhcp').Damien George
Fixes issue #5780.
2020-03-25all: Remove spaces between nested paren and inside function arg paren.Damien George
Using new options enabled in the uncrustify configuration.
2020-03-22esp8266/README.md: Add docker build instructions.Jim Mussared
2020-03-20esp8266/modmachine: Implement machine.soft_reset().Damien George
Fixes issue #5764.
2020-03-10esp8266/machine_pin: Disable ets_loop_iter during hard IRQ handler.Damien George
Otherwise ets_loop_iter may be reentered. Related to issue #5714.
2020-02-28all: Reformat C and Python source code with tools/codeformat.py.Damien George
This is run with uncrustify 0.70.1, and black 19.10b0.
2020-02-28all: Add *FORMAT-OFF* in various places.Damien George
This string is recognised by uncrustify, to disable formatting in the region marked by these comments. This is necessary in the qstrdef*.h files to prevent modification of the strings within the Q(...). In other places it is used to prevent excessive reformatting that would make the code less readable.
2020-02-13py: Add mp_raise_msg_varg helper and use it where appropriate.Damien George
This commit adds mp_raise_msg_varg(type, fmt, ...) as a helper for nlr_raise(mp_obj_new_exception_msg_varg(type, fmt, ...)). It makes the C-level API for raising exceptions more consistent, and reduces code size on most ports: bare-arm: +28 +0.042% minimal x86: +100 +0.067% unix x64: -56 -0.011% unix nanbox: -300 -0.068% stm32: -204 -0.054% PYBV10 cc3200: +0 +0.000% esp8266: -64 -0.010% GENERIC esp32: -104 -0.007% GENERIC nrf: -136 -0.094% pca10040 samd: +0 +0.000% ADAFRUIT_ITSYBITSY_M4_EXPRESS
2020-02-07esp8266: Put mp_keyboard_interrupt in IRAM.Damien George
It was originally in IRAM due to the linker script specification, but since the function moved from lib/utils/interrupt_char.c to py/scheduler.c it needs to be put back in IRAM.
2020-02-07py/scheduler: Add "raise_exc" argument to mp_handle_pending.Damien George
Previous behaviour is when this argument is set to "true", in which case the function will raise any pending exception. Setting it to "false" will cancel any pending exception.
2020-01-31esp8266/modules/ntptime.py: Add comment about configuring NTP host.Damien George
The ability to change the host is a frequently requested feature, so explicitly document how it can be achieved using the existing code. See issues #2121, #4385, #4622, #5122, #5536.
2020-01-14esp8266/modules: Fix AttributeError in _boot.py if flash not formatted.JensDiemer
Prior to this commit, if the flash filesystem was not formatted then it would error: "AttributeError: 'FlashBdev' object has no attribute 'mount'". That is due to it not being able to detect the filesystem on the block device and just trying to mount the block device directly. This commit fixes the issue by just catching all exceptions. Also it's not needed to try the mount if `flashbdev.bdev` is None.
2019-12-27ports: Allow overriding CROSS_COMPILE in a custom makefile.David Lechner
Many ports already allow overriding CROSS_COMPILE. This modifies the remaining ports to allow it as well.
2019-12-20extmod/webrepl: Move webrepl scripts to common place and use manifest.Jim Mussared
Move webrepl support code from ports/esp8266/modules into extmod/webrepl (to be alongside extmod/modwebrepl.c), and use frozen manifests to include it in the build on esp8266 and esp32. A small modification is made to webrepl.py to make it work on non-ESP ports, i.e. don't call dupterm_notify if not available.
2019-12-12py/persistentcode: Add ability to relocate loaded native code.Damien George
Implements text, rodata and bss generalised relocations, as well as generic qstr-object linking. This allows importing dynamic native modules on all supported architectures in a unified way.
2019-11-11extmod: Consolidate FAT FS config to MICROPY_VFS_FAT across all ports.Damien George
This commit removes the Makefile-level MICROPY_FATFS config and moves the MICROPY_VFS_FAT config to the Makefile level to replace it. It also moves the include of the oofatfs source files in the build from each port to a central place in extmod/extmod.mk. For a port to enabled VFS FAT support it should now set MICROPY_VFS_FAT=1 at the level of the Makefile. This will include the relevant oofatfs files in the build and set MICROPY_VFS_FAT=1 at the C (preprocessor) level.
