This is the Micro Python project, which aims to put an implementation of Python 3.x on a microcontroller.

Subdirectories:

• 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.

"make" is used to build the components.

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" 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.
