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.
If the Python code contains @native
or @viper
annotations, then you must
specify -march
to match the target architecture.
Run ./mpy-cross -h
to get a full list of options.
The optimisation level is 0 by default. Optimisation levels are detailed in https://docs.micropython.org/en/latest/library/micropython.html#micropython.opt_level
