Help¶

Enable LED strip driver for daisy chains of WS2812-ish (or WS2812B, WS2813, SK6812, or compatible) devices. These devices have a one-wire communications interface which encodes bits using pulses. Short pulses indicate zero bits, and long pulses indicate ones; refer to the chip datasheets for precise specifications. To implement this in a multitasking operating system, this driver generates the pulses using a SPI peripheral.

Direct dependencies¶
