A standard I2C address is 7 bits but addresses 0b0000xxx and 0b1111xxx are reserved. The scan() method is changed to reflect this, along with the docs.
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 MICROPY_PORT=<port_name> html
Where <port_name> can be unix, pyboard, wipy or esp8266.
You'll find the index page at micropython/docs/build/<port_name>/html/index.html.
