There are currently 7 ports that implement machine.WDT and a lot of code is duplicated across these implementations. This commit factors the common parts of all these implementations to a single location in extmod/machine_wdt.c. This common code provides the top-level Python bindings (class and method wrappers), and then each port implements the back end specific to that port. With this refactor the ports remain functionally the same except for: - The esp8266 WDT constructor now takes keyword arguments, and accepts the "timeout" argument but raises an exception if it's not the default value (this port doesn't support changing the timeout). - The mimxrt and samd ports now interpret the argument to WDT.timeout_ms() as signed and if it's negative truncate it to the minimum timeout (rather than it being unsigned and a negative value truncating to the maximum timeout).

The Renesas RA port
This is a port of MicroPython to the Renesas RA family of microcontrollers. Currently supported features are:
- Filesystem on the internal flash using FatFs.
timemodule with sleep, time, and ticks functions.osmodule with VFS support.machinemodule with the following classes:Pin,ADC,PWM,DAC,I2C,SPI,SoftI2C,SoftSPI,UART,RTC,SDCard.sdcardmodule for MCUs without nativemachine.SDCardsupport.
Currently supported board product names are:
- EK-RA6M2
- RA4M1 CLICKER
- EK-RA6M1
- EK-RA4M1
- EK-RA4W1
Please refer to the quick reference of renesas-ra port for more
information about the boards.
Build instructions
-
MicroPython cross-compier The MicroPython cross-compiler must be built first, which will be used to pre-compile (freeze) built-in Python code. THis cross-compiler is built and run on the host machine, using:
$ make -C mpy-crossThis command should be executed from the root directory of this repository. All other commands below should be executed from the ports/renesas-ra/ directory.
-
Arm compiler An
Arm compileris required for the build, along with the associated binary utilities. The default compiler isarm-none-eabi-gcc, which is available for Linux, Mac and Windows hosts via https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads. The compiler can be changed using theCROSS_COMPILEvariable when invokingmake. -
Protocol buffer compiler Building for the
ARDUINO_PORTENTA_C33board will build theesp_hosteddriver, that depends on the Protocol Buffer Compiler being installed. On Debian/Ubuntu, this can be installed withsudo apt-get install protobuf-compiler. -
Obtain submodules First the submodules must be obtained using:
$ make submodules -
Build binary image
.hexThen to build for a given board subdirectory name, run:$ make BOARD=EK_RA6M2 clean $ make BOARD=EK_RA6M2The default board subdirectory name is EK_RA6M2 (which is for EK-RA6M2 board) but any of the names of the subdirectories in the
boards/directory can be passed as the argument toBOARD=; for exampleRA4M1_CLICKER,EK_RA4M1,EK_RA4W1andEK_RA6M1. The above command should produce binary imagesfirmware.hexin the build-EK_RA6M2/` subdirectory (or the equivalent directory for the board specified).
