mpy-cross: Add new component, a cross compiler for MicroPython bytecode.
This component allows to generate .mpy files (pre compiled bytecode) which can be executed within any MicroPython runtime/VM.

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.
