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.
  • time module with sleep, time, and ticks functions.
  • os module with VFS support.
  • machine module with the following classes: Pin, ADC, PWM, DAC, I2C, SPI, SoftI2C, SoftSPI, UART, RTC, SDCard.
  • sdcard module for MCUs without native machine.SDCard support.

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-cross
    

    This 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 compiler is required for the build, along with the associated binary utilities. The default compiler is arm-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 the CROSS_COMPILE variable when invoking make.

  • Protocol buffer compiler Building for the ARDUINO_PORTENTA_C33 board will build the esp_hosted driver, that depends on the Protocol Buffer Compiler being installed. On Debian/Ubuntu, this can be installed with sudo apt-get install protobuf-compiler.

  • Obtain submodules First the submodules must be obtained using:

    $ make submodules
    
  • Build binary image .hex Then to build for a given board subdirectory name, run:

    $ make BOARD=EK_RA6M2 clean
    $ make BOARD=EK_RA6M2
    

    The 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 to BOARD=; for example RA4M1_CLICKER, EK_RA4M1, EK_RA4W1 and EK_RA6M1. The above command should produce binary images firmware.hex in the build-EK_RA6M2/` subdirectory (or the equivalent directory for the board specified).

Supported/Unsupprted funtions

Please refer to the renesas-ra quick reference.
