MicroPython cross compiler ========================== This directory contains the MicroPython cross compiler, which runs under any Unix-like system and compiles .py scripts into .mpy files. Build it as usual: $ make The compiler is called `mpy-cross`. Invoke it as: $ ./mpy-cross foo.py This will create a file foo.mpy which can then be copied to a place accessible by the target MicroPython runtime (eg onto a pyboard's filesystem), and then imported like any other Python module using `import foo`. Different target runtimes may require a different format of the compiled bytecode, and such options can be passed to the cross compiler. For example, the unix port of MicroPython requires the following: $ ./mpy-cross -mcache-lookup-bc foo.py Run `./mpy-cross -h` to get a full list of options.
