Important Notice

Because Unicorn HAT uses the PWM hardware, which is also how your Raspberry Pi generates analog audio, you may see random colour patterns and flickering.

If this happens, you should add the following to your /boot/config.txt:

hdmi_force_hotplug=1

Sound will work fine using speakers on, for example, an HDMI TV, but you will not be able to use your Pi's 3.5mm audio jack in conjunction with Unicorn HAT.

Based Upon rpi_ws281x

unicornhat is based upon a modified, Pi 2/3 compatible version of the RPi ws281x Library by Jeremy Garff.

The library was modified by Richard Hirst.

• Modified version: https://github.com/richardghirst/rpi_ws281x
• Original: https://github.com/jgarff/rpi_ws281x

RaspberryPi-NeoPixel-WS2812

Note: unicornhat is no longer based upon this library, but this information is included for posterity.

unicornhat was previously based upon a modified version of the ws2812 C driver from: https://github.com/626Pilot/RaspberryPi-NeoPixel-WS2812
