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.
WARNING: this project is in its early stages and is subject to large changes of the code-base, including project-wide name changes and API changes. The software will not start to mature until March 2014 at the earliest. For the moment the priority is the hardware.
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, or "gmake" on BSD-based systems.
The "unix" part requires a standard Unix environment with gcc and GNU make. 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])
Ubuntu and Mint derivatives will require build-essentials and libreadline-dev packages installed.
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.
