History

Damien George 03eae48847 extmod/machine_adc_block: Factor esp32 ADCBlock bindings to common code. This is a code factoring to have the Python bindings in one location, and all the ports use those same bindings. At this stage only esp32 implements this class, so the code for the bindings comes from that port. The documentation is also updated to reflect the esp32's behaviour of ADCBlock.connect().

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.
