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
