adafruit-circuitpython-ws2801 0.9.2

CircuitPython library for WS2801 LEDs.

Introduction

Higher level WS2801 driver that presents the LED string as a sequence. It is the same api as the NeoPixel library.

Colors are stored as tuples by default. However, you can also use int hex syntax to set values similar to colors on the web. For example, 0x800000 (#800000 on the web) is equivalent to (0x80, 0, 0).

Dependencies

This driver depends on:

• Adafruit CircuitPython

• Bus Device

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Usage Example

This example demonstrates the library driving a strand of 25 RGB leds by a Gemma M0 using the hardware SPI capable outputs.

import board
import adafruit_ws2801

leds = adafruit_ws2801.WS2801(board.D2, board.D0, 25)
leds.fill((0x80, 0, 0))

Building locally

Zip release files

To build this library locally you’ll need to install the circuitpython-build-tools package.

python3 -m venv .env
source .env/bin/activate
pip install circuitpython-build-tools

Once installed, make sure you are in the virtual environment:

source .env/bin/activate

Then run the build:

circuitpython-build-bundles --filename_prefix adafruit-circuitpython-ws2801 --library_location .

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

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.
