Detailed Description

lbuild module: modm:driver:sk9822

Drives any number of chained SK9822 RGB LEDs using SPI signals SCK and MOSI up to a few dozen MHz. Due to the synchronous clock, there are no special restrictions on protocol timing, making this driver safe to use with interrupts enabled and/or with an RTOS.

The internal data buffer size is 4B for start of frame, 4B for every LED and 1B for every 16 LEDs as end of frame.
