The Micro Python project
========================
<p align="center">
<img src="https://raw2.github.com/micropython/micropython/master/logo/upython-with-micro.jpg" alt="MicroPython Logo"/>
</p>
This is the Micro Python project, which aims to put an implementation
of Python 3.x on a microcontroller.
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.
See the repository www.github.com/micropython/pyboard for the Micro
Python board. At the moment, finalising the design of the board is
the top priority.
Major components in this repository:
- 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.
- teensy/ -- a version of Micro Python that runs on the Teensy 3.1
(preliminary but functional).
Additional components:
- unix-cpy/ -- a version of Micro Python that outputs bytecode (for testing).
- tests/ -- test framework and test scripts.
- tools/ -- various tools.
- examples/ -- a few example Python scripts.
"make" is used to build the components, or "gmake" on BSD-based systems.
You will also need bash and python (2.7 or 3.3) for the stm port.
The Unix version
----------------
The "unix" part requires a standard Unix environment with gcc and GNU make.
x86 and x64 architectures are supported (i.e. x86 32- and 64-bit). ARM to
be confirmed. Porting to other architectures require writing some assembly
code for the exception handling.
To build:
$ cd unix
$ make
Then to test it:
$ ./micropython
>>> list(5 * x + y for x in range(10) for y in [4, 2, 1])
Debian/Ubuntu/Mint derivative Linux distros will require build-essentials and
libreadline-dev packages installed. To build FFI (Foreign Function Interface)
module (recommended, enable in unix/mpconfigport.mk), libffi-dev is required.
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.
