The Micro Python project
|
|
========================

|
|
|
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.
|
|
|
|
See the repository www.github.com/micropython/pyboard for the Micro
|
|
Python board.
|
|
|
|
Major components in this repository:
|
|
- py/ -- the core Python implementation, including compiler and runtime.
|
|
- unix/ -- a version of Micro Python that runs on Unix.
|
|
- stmhal/ -- a version of Micro Python that runs on the Micro Python board
|
|
with an STM32F405RG (using ST's new Cube HAL drivers).
|
|
- teensy/ -- a version of Micro Python that runs on the Teensy 3.1
|
|
(preliminary but functional).
|
|
|
|
Additional components:
|
|
- bare-arm/ -- a bare minimum version of Micro Python for ARM MCUs. Start
|
|
with this if you want to port Micro Python to another microcontroller.
|
|
- stm/ -- obsolete version of Micro Python for the Micro Python board
|
|
that uses ST's old peripheral drivers.
|
|
- unix-cpy/ -- a version of Micro Python that outputs bytecode (for testing).
|
|
- tests/ -- test framework and test scripts.
|
|
- tools/ -- various tools, including the pyboard.py module.
|
|
- 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 (at least 2.7 or 3.3).
|
|
|
|
The Unix version
|
|
----------------
|
|
|
|
The "unix" port requires a standard Unix environment with gcc and GNU make.
|
|
x86 and x64 architectures are supported (i.e. x86 32- and 64-bit), as well
|
|
as ARMv7. 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, libffi-dev package is required. If you have problems with some
|
|
dependencies, they can be disabled in unix/mpconfigport.mk .
|
|
|
|
The STM version
|
|
---------------
|
|
|
|
The "stmhal" port 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 stmhal
|
|
$ make
|
|
|
|
You then need to get your board into DFU mode. On the pyboard, connect the
|
|
3V3 pin to the P1/DFU pin with a wire (on PYBv1.0 they are next to each other
|
|
on the bottom left of the board, second row from the bottom).
|
|
|
|
Then to flash the code 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.
