The Micro Python project

This is the Micro Python project, which aims to put an implementation of Python 3.x on a microcontroller. The project also includes a small microcontroller board based around the STM32F405RG.

Major components:

py/ -- the core Python implementation, including compiler and runtime.
unix/ -- a version of Micro Python that runs on Unix.
stm/ -- a version of Micro Python that runs on the Micro Python board with an STM32F405RG.
pybv3/ -- schematics, gerbers and EAGLE files for revision 3 of the Micro Python board.

Additional components:

unix-cpy/ -- a version of Micro Python that outputs bytecode (for testing).
tests/ -- test framework and test scripts.
tools/ -- various tools.

"make" is used to build the components.

The Unix version

The "unix" part requires a standard Unix environment with gcc. It works only for 64-bit machines due to a small piece of x86-64 assembler for the exception handling.

To build:

$ cd unix
$ make

Then to test it:

$ ./py
>>> list(5 * x + y for x in range(10) for y in [4, 2, 1])

The STM version

The "stm" part requires an ARM compiler, arm-none-eabi-gcc, and associated bin-utils. For those using Arch Linux, you need arm-none-eabi-binutils and arm-none-eabi-gcc packages from the AUR. Otherwise, try here: https://launchpad.net/gcc-arm-embedded

To build:

$ cd stm
$ make

Then to flash it via USB DFU to your device:

$ dfu-util -a 0 -D build/flash.dfu

You will need the dfu-util program, on Arch Linux it's dfu-util-git in the AUR.
