NeoPixel Python

A thread-based Python library to control WS281X LEDs (AdaFruits NeoPixels).

Installation

(Dependencies are installed automatically with this method.)

git clone https://github.com/So-Cool/neopixel-python.git
cd neopixel-python
pip install .

Dependencies

This library requires rpi_ws281x and its corresponding Python library. It can be installed either with pip (recommended) or manually -- see below. Detailed installation instructions are available on AdaFruit's website.

Dependency Installation via pip

sudo pip install rpi_ws281x

Manual Dependency Installation

If you want to install the rpi_ws281x library manually:

# Update OS packages
sudo apt-get update
sudo apt-get install build-essential python-dev git scons swig

# Install WS281X driver...
git clone https://github.com/jgarff/rpi_ws281x.git
cd rpi_ws281x
scons

# ...and the corresponding Python package
sudo pip install rpi_ws281x
# `cd python && sudo python setup.py install` has been deprecated

---

Test with: rpi_ws281x/python/examples/strandtest.py. Adjust LED_PIN to 13 or 18 and LED_CHANNEL 0 to 1.

Notes

This library is distributed with a file (neopixel_python/neopixel.py) adapted from the rpi_ws281x library. It is required for the proper functioning of this package but it is not distributed with the pip's version of rpi_ws281x, which superseded the Python library distributed as a part of rpi_ws281x.

To Do

• Consider Unicorn Hat as a Linux service written in C and controlled from Python instead. Also have a look at Unicorn Paint and OctaPi's use of Unicorn Hat.
