mpy-cross is the micropython cross compiler utility, used to pre-compile python files into bytecode suitable for running on your target.
|
||
|
|
|
||
|
|
This project compiles mpy-cross for windows, linux and macos and distributes them in python wheels for easy installation on development pc's.

Version
|
||
|
|
-------
|
||
|
|
|
||
|
|
The release version of this package directly corresponds to the micropython release it's built against.
|
||
|
|
|
||
|
|
If a wrapper update is needed for a particular release version, it will be updloaded with a `.postN` version
|
||
|
|
|
||
|
|
Weekly releases build against master should be available at: https://gitlab.com/alelec/mpy_cross/pipelines
|
||
|
|
These will have version numbers that reflect the previous release and the current git hash built against.
|
||
|
|
|
||
|
|
Usage
|
||
|
|
-----
|
||
|
|
mpy-cross can be run in three different ways
|
||
|
|
|
||
|
|
* From python command line ::
|
||
|
|
|
||
|
|
python -m mpy_cross <args>
|
||
|
|
python -m mpy_cross --version
|
||
|
|
|
||
|
|
* From python code ::
|
||
|
|
|
||
|
|
import mpy_cross
|
||
|
|
|
||
|
|
mpy_cross.run(*args, **kwargs)
|
||
|
|
|
||
|
|
import subprocess
|
||
|
|
proc = mpy_cross.run('--version', stdout=subprocess.PIPE)
|
||
|
|
|
||
|
|
where `*args` are arguments passed to mpy-cross, `**kwargs` are arguments to pass to `subprocess.Popen()` internally
|
||
|
|
|
||
|
|
* Standalone ::
|
||
|
|
|
||
|
|
# Print out path to actual mpy-cross exe
|
||
|
|
python -c "import mpy_cross; print(mpy_cross.mpy_cross)"

|
||
|
|
-o : output file for compiled bytecode (defaults to input with .mpy extension)
|
||
|
|
