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.
utimemodule with sleep, time, and ticks functions.uosmodule with VFS support.machinemodule with the following classes:Pin,ADC,I2C,SPI,SoftI2C,SoftSPI,UART,RTC- sdcard driver if frozen driver is installed.
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 Arch Linux and Windows hosts via https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads. The compiler can be changed using theCROSS_COMPILEvariable when invokingmake. -
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=RA6M2_EK clean $ make BOARD=RA6M2_EKThe default board subdirectory name is RA6M2_EK (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,RA4M1_EK,RA4W1_EKandRA6M1_EK. The above command should produce binary imagesfirmware.hexin the build-RA6M2_EK/` subdirectory (or the equivalent directory for the board specified).
Supported/Unsupprted funtions
Please refer to the renesas-ra quick reference.
