Fusion_STM32

Port for MicroPython language on STM32 developed for Fusion for ARM v8.

Prepare

You are required to init submodules and install required compilers. Required compilers are GCC/G++ (GNU SDK) for ARM.
Submodule initialization:

git submodule update --init lib/micropython
cd lib/micropython
git submodule update --init lib/stm32lib lib/mbedtls lib/lwip lib/micropython-lib

Compiling required cross compiler for MP:

make -C lib/micropython/mpy-cross

Build

To build a firmware for choosen development board, you need to do following. The firmware will be located at boards/<dev_board>/build/firmware.hex.

cd boards/<dev_board>
make -j$(nproc) LTO=1 DEBUG=0 LOWMEM=1

LTO (Link Time Optimisation) usually shrinks .hex file for 2-3%. Not recommended in usage when MbedTLS is enabled. DEBUG stands to enable debugging symbols for GDB. LOWMEM is used to build a firmware for Low Memory MCU or normal (> 1024KB flash size). Differences are explained in LATEST.md.

Alternate Function file generation

To generate a Alternate Function file, and later use it for specific MCU port, execute following Python script:

python3 make_af.py <stm32_mcu_name>

The source for the script is from micropython main repository.

TODO, future releases, support

Port currently DOES NOT support TFT SSD19603 controller.
However, plans are to add LVGL support.

STM32 family

This MPY port supports following STM32 families (some of them are ported):

(*) With minimal possible usage beacuse of memory limit & other things
(!) May not all alternate functions (LAN, BLE, Wi-Fi) usable or developed

Release

The ports are automatically built by GitHub Actions on every new commit. Check the latest release to find a HEX file for your MCU.

Required header

On every file that uses this port, please add this header:

C/C++

/* Port written by Uglješa Lukešević (@ukicomputers)            *
 * MicroPython licensed with MIT license under Damien P. George */

Python

"""

It is also required when calling help() in MicroPython firmware to output show that port is written by me. That is already set up.

If use this port in NECTO, also in About section, define that port is written by me, exactly like this:
