This is the source code for MiniPython running on the BBC micro:bit with additional features based on the original MicroPython version for the BBC micro:bit!

NOTE - This is a new fork and in early stages of development. Please be patient as this develops out. The goal is to help educators have an active fork to add custom functionality to their curriculum.

Various things are in this repository, including:

• Source code in source/ and inc/ directories.
• Example Python programs in the examples/ directory.
• Tools in the tools/ directory.
• Integrated Friend module chatbot.

The source code is a yotta application and needs yotta to build, along with an ARM compiler toolchain (eg arm-none-eabi-gcc and friends).

Ubuntu users can install the needed packages using:

sudo add-apt-repository -y ppa:team-gcc-arm-embedded
sudo add-apt-repository -y ppa:pmiller-opensource/ppa
sudo apt-get update
sudo apt-get install cmake ninja-build gcc-arm-none-eabi srecord libssl-dev
pip3 install yotta

Once all packages are installed, use yotta and the provided Makefile to build. You might need need an Arm Mbed account to complete some of the yotta commands, if so, you could be prompted to create one as a part of the process.

• Use target bbc-microbit-classic-gcc-nosd:

  yotta target bbc-microbit-classic-gcc-nosd
  

• Run yotta update to fetch remote assets:

  yotta up
  

• Start the build:

  make all
  

The resulting firmware.hex file to flash onto the device can be found in the build/ directory from the root of the repository.

The Makefile provided does some extra preprocessing of the source, adds version information to the UICR region, puts the resulting firmware at build/firmware.hex, and includes some convenience targets.

Upon reset you will have a REPL on the USB CDC serial port, with baudrate 115200 (eg picocom /dev/ttyACM0 -b 115200).

Then try:

>>> import microbit
>>> microbit.display.scroll('hello!')
>>> microbit.button_a.is_pressed()
>>> dir(microbit)

Tab completion works and is very useful!

You can also use the tools/pyboard.py script to run Python scripts directly from your PC, eg:

$ ./tools/pyboard.py /dev/ttyACM0 examples/conway.py
