Help¶

SPI clock rate, in Hz, to use while driving the strip. The baud rate must be chosen carefully together with the WS2812_STRIP_SPI_ONE_FRAME and WS2812_STRIP_SPI_ZERO_FRAME values so that the transmitted frames meet the chipset pulse widths for one and zero bits. If unsure, keep the default, but enable SPI debug logging for your device and make sure the configuration is matched exactly at runtime.

Direct dependencies¶

WS2812_STRIP && LED_STRIP

(Includes any dependencies from if’s and menus.)

Defaults¶

5250000 if WS2812_STRIP && LED_STRIP
