ML4F MicroPython module proof of concept

An experiment to integrate ML4F into MicroPython.

Build instructions

Clone this repository and initialise the git submodules (recursive submodule init will unnecessarily initialise all submodules from all MicroPython ports):

git clone https://github.com/microbit-foundation/micropython-ml4f-poc.git
cd micropython-ml4f-poc
git submodule update --init
git -C micropython-microbit-v2 submodule update --init
git -C ml-module/pxt-ml-runner-poc submodule update --init

Changes to the micro:bit MicroPython port are required for this experiment:

git -C micropython-microbit-v2 apply ../micropython-microbit-v2.patch

Build MicroPython's mpy-cross:

make -C micropython-microbit-v2/lib/micropython/mpy-cross

And build MicroPython with the ML module (and example model) included:

make -C micropython-microbit-v2/src USER_C_MODULES=../../..

Copy the hex file to the micro:bit:

cp micropython-microbit-v2/src/build/MICROBIT.hex /Volumes/MICROBIT

Transfer the example Python code into the board with microFS:

ufs put ml-module/model-example/main.py
