uos.compile(source_file, mpy_file=None)

This is an XBee extension to uos. Compile Python source code in source_file and store in a file with an .mpy extension. Default is to remove the .py extension from source_file and append .mpy to generate mpy_file. See Import modules from file system for details on using .mpy files.

Compilation involves three steps: parsing, compiling and saving to the file system. MicroPython prints information about heap usage before each step so you can monitor heap requirements for a device, and consider splitting it into two (or more) modules or compiling with the MicroPython cross compiler (mpy-cross) on your computer instead of compiling on the XBee device.
