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
