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

|
|
|
|
This is the Micro Python project, which aims to put an implementation
|
|
of Python 3.x on microcontrollers and small embedded systems.
|
|
|
|
WARNING: this project is in beta stage and is subject to changes of the
|
|
code-base, including project-wide name changes and API changes.
|
|
|
|
Micro Python implements the entire Python 3.4 syntax (including exceptions,
|
|
"with", "yield from", etc.). The following core datatypes are provided:
|
|
str (including basic Unicode support), bytes, bytearray, tuple, list, dict,
|
|
set, frozenset, array.array, collections.namedtuple, classes and instances.
|
|
Builtin modules include sys, time, and struct. Note that only subset of
|
|
Python 3.4 functionality implemented for the data types and modules.
|
|
|
|
See the repository www.github.com/micropython/pyboard for the Micro
|
|
Python board, the officially supported reference electronic circuit board.
|
|
|
|
Major components in this repository:
|
|
- py/ -- the core Python implementation, including compiler, runtime, and
|
|
core library.
|
|
- 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 Cube HAL drivers).
|
|
- minimal/ -- a minimal Micro Python port. Start with this if you want
|
|
to port Micro Python to another microcontroller.
|
|
|
|
Additional components:
|
|
- bare-arm/ -- a bare minimum version of Micro Python for ARM MCUs. Used
|
|
mostly to control code size.
|
|
- teensy/ -- a version of Micro Python that runs on the Teensy 3.1
|
|
(preliminary but functional).
|
|
- 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.
|
|
- docs/ -- official documentation in RST format.
|
|
|
|
"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 ARM and MIPS. Making full-featured port to another architecture requires
|
|
writing some assembly code for the exception handling and garbage collection.
|
|
Alternatively, fallback implementation based on setjmp/longjmp can be used.
|
|
|
|
To build:
|
|
|
|
$ cd unix
|
|
$ make
|
|
|
|
Then to give it a try:
|
|
|
|
$ ./micropython
|
|
>>> list(5 * x + y for x in range(10) for y in [4, 2, 1])
|
|
|
|
Run complete testsuite:
|
|
|
|
$ make test
|
|
|
|
Debian/Ubuntu/Mint derivative Linux distros will require build-essentials and
|
|
libreadline-dev packages installed. To build FFI (Foreign Function Interface)
|
|
module, libffi-dev and pkg-config packages are 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:
|
|
|
|
$ make deploy
|
|
|
|
You will need the dfu-util program, on Arch Linux it's dfu-util-git in the
|
|
AUR. If the above does not work it may be because you don't have the
|
|
correct permissions. Try then:
|
|
|
|
$ sudo dfu-util -a 0 -d 0483:df11 -D build-PYBV10/firmware.dfu
|
|
|
|
Building the documentation locally
|
|
----------------------------------
|
|
|
|
Install Sphinx, and optionally (for the RTD-styling), sphinx_rtd_theme,
|
|
preferably in a virtualenv:
|
|
|
|
pip install sphinx
|
|
pip install sphinx_rtd_theme
|
|
|
|
In `micropython/docs`, build the docs:
|
|
|
|
make html
|
|
|
|
You'll find the index page at `micropython/docs/build/html/index.html`.
