|

|
|
||||||
|
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`/`await` keywords 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`, etc. Select ports have
|
||||||
|
support for `_thread` module (multithreading). Note that only a subset of
|
||||||
|
Python 3 functionality is implemented for the data types and modules.
|
||||||
|
|
||||||
|
MicroPython can execute scripts in textual source form or from precompiled
|
||||||
|
bytecode, in both cases either from an on-device filesystem or "frozen" into
|
||||||
|
the MicroPython executable.
|
||||||
|
|
||||||
|
See the repository http://github.com/micropython/pyboard for the MicroPython
|
||||||
|
board (PyBoard), the officially supported reference electronic circuit board.
|
||||||
|
|
||||||
|

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, gcc, and Python 3.3+ available as the command `python3`
|
||||||
|
(if your system only has Python 2.7 then invoke make with the additional option
|
||||||
|
`PYTHON=python2`).
|
||||||
|
|
||||||
|
The MicroPython cross-compiler, mpy-cross
|
||||||
|
-----------------------------------------
|
||||||
|
|
||||||
|
Most ports require the MicroPython cross-compiler to be built first. This
|
||||||
|
program, called mpy-cross, is used to pre-compile Python scripts to .mpy
|
||||||
|
files which can then be included (frozen) into the firmware/executable for
|
||||||
|
a port. To build mpy-cross use:
|
||||||
|
|
||||||
|
$ cd mpy-cross
|
||||||
|
$ make
|
||||||
|
|
||||||
|
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 ports/unix
|
||||||
|
$ make submodules
|
||||||
|
$ 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 MicroPython ports may require some dependencies installed.
|
||||||
|
|
||||||
|
For Unix port, `libffi` library and `pkg-config` tool are required. On
|
||||||
|
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. This may
|
||||||
|
be required to enable extra features or capabilities, and in recent
|
||||||
|
versions of MicroPython, these may be enabled by default. To build
|
||||||
|
these additional dependencies, in the port directory you're
|
||||||
|
interested in (e.g. `ports/unix/`) first execute:
|
||||||
|
|
||||||
|
$ make submodules
|
||||||
|
|
||||||
|
This will fetch all the relevant git submodules (sub repositories) that
|
||||||
|
the port needs. Use the same command to get the latest versions of
|
||||||
|
submodules as they are updated from time to time. After that 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 enable/disable use of dependencies, edit
|
||||||
|
`ports/unix/mpconfigport.mk` file, which has inline descriptions of the options.
|
||||||
|
For example, to build SSL module (required for `upip` tool described above,
|
||||||
|
and so enabled by dfeault), `MICROPY_PY_USSL` should be set to 1.
|
||||||
|
|
||||||
|
For some ports, building required dependences is transparent, and happens
|
||||||
|
automatically. But they still need to be fetched with the `make submodules`
|
||||||
|
command.
|
||||||
|
|
||||||
|
The STM32 version
|
||||||
|
-----------------
|
||||||
|
|
||||||
|
The "stm32" port requires an ARM compiler, arm-none-eabi-gcc, and associated
|
||||||
|
bin-utils. For those using Arch Linux, you need arm-none-eabi-binutils,
|
||||||
|
arm-none-eabi-gcc and arm-none-eabi-newlib packages. Otherwise, try here:
|
||||||
|
https://launchpad.net/gcc-arm-embedded
|
||||||
|
|
||||||
|
To build:
|
||||||
|
|
||||||
|
$ cd ports/stm32
|
||||||
|
$ make submodules
|
||||||
|
$ 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 ports/stm32/ directory for further details.

|
|
||||||
|
|
||||||
The STM32 version
|
|
||||||
-----------------
|
|
||||||
|
|
||||||
The "stm32" port requires an ARM compiler, arm-none-eabi-gcc, and associated
|
|
||||||
bin-utils. For those using Arch Linux, you need arm-none-eabi-binutils,
|
|
||||||
arm-none-eabi-gcc and arm-none-eabi-newlib packages. Otherwise, try here:
|
|
||||||
https://launchpad.net/gcc-arm-embedded
|
|
||||||
|
|
||||||
To build:
|
|
||||||
|
|
||||||
$ cd ports/stm32
|
|
||||||
$ make submodules
|
|
||||||
$ make
|
|
||||||
|
|
