CircuitPython APIs for non-CircuitPython versions of Python such as CPython on Linux and MicroPython.

Project description

Introduction

Documentation Status Discord Build Status Code Style: Black

This repository contains a selection of packages emulating the CircuitPython API for devices or hosts running CPython or MicroPython. Working code exists to emulate these CircuitPython packages:

  • analogio - analog input/output pins, using pin identities from board+microcontroller packages

  • bitbangio - software-driven interfaces for I2C, SPI

  • board - breakout-specific pin identities

  • busio - hardware-driven interfaces for I2C, SPI, UART

  • digitalio - digital input/output pins, using pin identities from board+microcontroller packages

  • keypad - support for scanning keys and key matrices

  • microcontroller - chip-specific pin identities

  • micropython - MicroPython-specific module

  • neopixel_write - low-level interface to NeoPixels

  • pulseio - contains classes that provide access to basic pulse IO (PWM)

  • pwmio - contains classes that provide access to basic pulse IO (PWM)

  • rainbowio - provides the colorwheel() function

  • usb_hid - act as a hid-device using usb_gadget kernel driver

For details, see the Blinka API reference.

Dependencies

The emulation described above is intended to provide a CircuitPython-like API for devices which are running CPython or Micropython. Since corresponding packages should be built-in to any standard CircuitPython image, they have no value on a device already running CircuitPython and would likely conflict in unhappy ways.

The test suites in the test/src folder under testing.universal are by design intended to run on either CircuitPython or CPython/Micropython+compatibility layer to prove conformance.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install Adafruit-Blinka

To install system-wide (this may be required in some cases):

sudo pip3 install Adafruit-Blinka

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install Adafruit-Blinka

Usage Example

At the time of writing (git:7fc1f8ab), the following sequence runs through some basic testing of the digitalio compatibility layer…

from testing import test_module_name
test_module_name("testing.universal.digitalio")

An example log from running the suites is here .

Building locally

Sphinx documentation

Sphinx is used to build the documentation based on rST files and comments in the code. First, install dependencies (feel free to reuse the virtual environment from above):

python3 -m venv .env
source .env/bin/activate
pip install Sphinx sphinx-rtd-theme Adafruit-PlatformDetect

Now, once you have the virtual environment activated:

cd docs
sphinx-build -E -W -b html . _build/html

This will output the documentation to docs/_build/html. Open the index.html in your browser to view them. It will also (due to -W) error out on any warning like Travis will. This is a good way to locally verify it will pass.
