Zephyr v3.7.0 added a new feature to allow getting devices by their
devicetree node labels. Use this feature in the MicroPython Zephyr port
to simplify constructing machine module objects, including Pin, SPI,
I2C, and UART. It's still possible to use the more verbose device names
(e.g., gpio@400ff040, i2c@40066000, spi@4002c000), but now we can also
use their devicetree node labels (e.g., gpiob, i2c0, spi0).
Node labels aren't standardized across all SoC families because they
generally try to follow their respective SoC hardware user manual naming
convention, however many boards define common labels for devices routed
to Arduino headers (e.g., arduino_i2c, arduino_serial, and arduino_spi).
That means I2C("arduino_i2c") will work on quite a few boards (>100 in
the main Zephyr tree).

MicroPython Documentation
The MicroPython documentation can be found at: http://docs.micropython.org/en/latest/
The documentation you see there is generated from the files in the docs tree: https://github.com/micropython/micropython/tree/master/docs
Building the documentation locally
If you're making changes to the documentation, you may want to build the documentation locally so that you can preview your changes.
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.
Having readthedocs.org build the documentation
If you would like to have docs for forks/branches hosted on GitHub, GitLab or BitBucket an alternative to building the docs locally is to sign up for a free https://readthedocs.org account. The rough steps to follow are:
- sign-up for an account, unless you already have one
- in your account settings: add GitHub as a connected service (assuming you have forked this repo on github)
- in your account projects: import your forked/cloned micropython repository into readthedocs
- in the project's versions: add the branches you are developing on or for which you'd like readthedocs to auto-generate docs whenever you push a change
PDF manual generation
This can be achieved with:
make latexpdf
but requires a rather complete install of LaTeX with various extensions. On Debian/Ubuntu, try (1GB+ download):
apt install texlive-latex-recommended texlive-latex-extra texlive-xetex texlive-fonts-extra cm-super xindy
