The MicroPython project
|
|
=======================
|

</p>
|
|
|
|
This is the MicroPython project, which aims to put an implementation
|
|
of Python 3.x on microcontrollers and small embedded systems.
|
|
You can find the official website at [micropython.org](http://www.micropython.org).
|
|
|
|
WARNING: this project is in beta stage and is subject to changes of the
|
|
code-base, including project-wide name changes and API changes.
|
|
|
|
MicroPython implements the entire Python 3.4 syntax (including exceptions,
|
|
"with", "yield from", etc., and additionally "async" keyword from Python 3.5).
|
|
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 MicroPython that runs on Unix.
|
|
- stmhal/ -- a version of MicroPython that runs on the MicroPython board
|
|
with an STM32F405RG (using ST's Cube HAL drivers).
|
|
- minimal/ -- a minimal MicroPython port. Start with this if you want
|
|
to port MicroPython to another microcontroller.
|
|
- tests/ -- test framework and test scripts.
|
|
- docs/ -- user documentation in Sphinx reStructuredText format.
|
|
|
|
Additional components:
|
|
- bare-arm/ -- a bare minimum version of MicroPython for ARM MCUs. Used
|
|
mostly to control code size.
|
|
- teensy/ -- a version of MicroPython that runs on the Teensy 3.1
|
|
(preliminary but functional).
|
|
- pic16bit/ -- a version of MicroPython for 16-bit PIC microcontrollers.
|
|
- cc3200/ -- a version of MicroPython that runs on the CC3200 from TI.
|
|
- esp8266/ -- an experimental port for ESP8266 WiFi modules.
|
|
- tools/ -- various tools, including the pyboard.py module.
|
|
- examples/ -- a few example Python scripts.
|
|
|
|
The subdirectories above may include READMEs with additional info.
|
|
|
|
"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 (see section below for required dependencies):
|
|
|
|
$ 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])
|
|
|
|
Use `CTRL-D` (i.e. EOF) to exit the shell.
|
|
Learn about command-line options (in particular, how to increase heap size
|
|
which may be needed for larger applications):
|
|
|
|
$ ./micropython --help
|
|
|
|
Run complete testsuite:
|
|
|
|
$ make test
|
|
|
|
Unix version comes with a builtin package manager called upip, e.g.:
|
|
|
|
$ ./micropython -m upip install micropython-pystone
|
|
$ ./micropython -m pystone
|
|
|
|
Browse available modules on
|
|
[PyPI](https://pypi.python.org/pypi?%3Aaction=search&term=micropython).
|
|
Standard library modules come from
|
|
[micropython-lib](https://github.com/micropython/micropython-lib) project.
|
|
|
|
External dependencies
|
|
---------------------
|
|
|
|
Building Unix version requires some dependencies installed. For
|
|
Debian/Ubuntu/Mint derivative Linux distros, install `build-essential`
|
|
(includes toolchain and make), `libffi-dev`, and `pkg-config` packages.
|
|
|
|
Other dependencies can be built together with MicroPython. Oftentimes,
|
|
you need to do this to enable extra features or capabilities. To build
|
|
these additional dependencies, first fetch git submodules for them:
|
|
|
|
$ git submodule update --init
|
|
|
|
Use this same command to get the latest versions of dependencies, as
|
|
they are updated from time to time. After that, in `unix/` dir, execute:
|
|
|
|
$ make deplibs
|
|
|
|
This will build all available dependencies (regardless whether they
|
|
are used or not). If you intend to build MicroPython with additional
|
|
options (like cross-compiling), the same set of options should be passed
|
|
to `make deplibs`. To actually enabled use of dependencies, edit
|
|
`unix/mpconfigport.mk` file, which has inline descriptions of the options.
|
|
For example, to build SSL module (required for `upip` tool described above),
|
|
set `MICROPY_PY_USSL` to 1.
|
|
|
|
In `unix/mpconfigport.mk`, you can also disable some dependencies enabled
|
|
by default, like FFI support, which requires libffi development files to
|
|
be installed.
|
|
|
|
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. 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
|
|
|
|
This will use the included `tools/pydfu.py` script. If flashing the firmware
|
|
does not work it may be because you don't have the correct permissions, and
|
|
need to use `sudo make deploy`.
|
|
See the README.md file in the stmhal/ directory for further details.
