Struct ws2812_spi::prerendered::Ws2812

pub struct Ws2812<'a, SPI> { /* fields omitted */ }

Methods

impl<'a, SPI, E> Ws2812<'a, SPI> where
    SPI: FullDuplex<u8, Error = E>, 

pub fn new(spi: SPI, timing: Timing, data: &'a mut [u8]) -> Ws2812<'a, SPI>

The SPI bus should run exactly with the provided frequency

You may need to look at the datasheet and your own hal to verify this.

You need to provide a buffer data, whoose length is at least 3 the length of the led strip. You can calculate the exact amount for frequencies >= 3 MHz with "spi frequency / 1_100_00" rounded up
