This action provides the following functionality for GitHub Actions users:

• Builds and installs the following executables:
  • micropython - The micropython runtime. Can be used to run unit tests in conjunction with libraries such as micropython's unittest.
  • mpy-cross - The micropython cross-compiler. Used to cross-compile precompiled bytecode for specific microcontroller architectures.
• Provides a clone of the micropython repository and sets the environment variable MPY_DIR to it's path.
  • Can be used as for artifact building, like using native machine code in mpy files.
• Builds are automatically cached, speeding up subsequent runs.

Simply add the following step to your workflow:

steps:
  - name: Install MicroPython
