20 This repository contains a selection of packages mirroring the CircuitPython API
21 on hosts running micropython. Working code exists to emulate the CircuitPython packages;
23 * **board** - breakout-specific pin identities
24 * **microcontroller** - chip-specific pin identities
25 * **analogio** - analog input/output pins, using pin identities from board+microcontroller packages
26 * **digitalio** - digital input/output pins, using pin identities from board+microcontroller packages
27 * **bitbangio** - software-driven interfaces for I2C, SPI
28 * **busio** - hardware-driven interfaces for I2C, SPI, UART
29 * **time** * - substitute functions monkey-patched to time module
35 The Micropython compatibility layers described above are intended to provide a CircuitPython-like API for devices which
36 are running CPython or Micropython. Since corresponding packages should be built-in to any standard
37 CircuitPython image, they have no value on a device already running CircuitPython and would likely conflict in unhappy ways.
39 The test suites in the test/src folder under **testing.universal** are by design
40 intended to run on *either* CircuitPython *or* Micropython+compatibility layer to prove conformance.
45 On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally `from
46 PyPI <https://pypi.org/project/Adafruit-Blinka/>`_. To install for current user:
50 pip3 install Adafruit-Blinka
52 To install system-wide (this may be required in some cases):
56 sudo pip3 install Adafruit-Blinka
58 To install in a virtual environment in your current project:
62 mkdir project-name && cd project-name
64 source .env/bin/activate
65 pip3 install Adafruit-Blinka
70 At the time of writing (`git:7fc1f8ab <https://github.com/cefn/Adafruit_Micropython_Blinka/tree/7fc1f8ab477124628a5afebbf6826005955805f9>`_),
71 the following sequence runs through some basic testing of the digitalio compatibility layer...
73 .. code-block:: python
75 from testing import test_module_name
76 test_module_name("testing.universal.digitalio")
78 An example log from running the suites is `here <https://github.com/cefn/Adafruit_Micropython_Blinka/issues/2#issuecomment-366713394>`_ .

91 -----------------------
93 Sphinx is used to build the documentation based on rST files and comments in the code. First,
94 install dependencies (feel free to reuse the virtual environment from above):
99 source .env/bin/activate
100 pip install Sphinx sphinx-rtd-theme
102 Now, once you have the virtual environment activated:
104 .. code-block:: shell
107 sphinx-build -E -W -b html . _build/html
109 This will output the documentation to ``docs/_build/html``. Open the index.html in your browser to
110 view them. It will also (due to -W) error out on any warning like Travis will. This is a good way to
111 locally verify it will pass.
