Neopixel Display

A 2d Go drawing library for Rapsberry Pi driven Neopixels

Install

go get github.com/fresh4less/neopixel-display

Build

go install

To build with Raspberry Pi neopixel support using the rpi_ws281x library:

  1. Ensure the ws281x header files pwm.h, rpihw.h, and ws2811.h, are in /usr/include
  2. Ensure the ws281x library file ws2811.a is in /usr/lib
  3. Run go install

The library also provides a command-line visualization to help develop on a machine that isn't connected to LEDs. Build with go install -tags noled.
