A userspace C library for controlling WS281X LED strips (WS2812, SK6812 RGB/RGBW) from a Raspberry Pi via PWM, PCM, or SPI with DMA. It includes a test program and has official bindings for Python, Rust, Go, Java, C#, and other languages.

Use cases

  • drive neopixel led strips from a raspberry pi
  • control ws2812b addressable leds in c
  • light up an 8x8 led matrix like unicorn hat
  • control sk6812 rgbw leds on a pi
  • drive led strips over spi or pwm on raspberry pi
  • use dma to control long chains of addressable leds

When to avoid

  • you are on a non-Raspberry-Pi platform or a Pi 5 without compatible support
  • you want a high-level animation framework rather than raw LED control
  • you need to drive LEDs other than WS281X/SK6812 types
