Struct Ws2811

pub struct Ws2811<'a, SPI, DEVICE = Ws2811> { /* private fields */ }

Implementations

impl<'a, SPI, E> Ws2811<'a, SPI>

where SPI: FullDuplex<u8, Error = E>,

pub fn new(spi: SPI, data: &'a mut [u8]) -> Self

Use Ws2811 devices via spi

The SPI bus should run within 2 MHz to 3.8 MHz

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 12 * the length of the led strip + 20 byes (or 40, if using the mosi_idle_high feature)

Please ensure that the mcu is pretty fast, otherwise weird timing issues will occur

fn write<T, I>(&mut self, iterator: T) -> Result<(), Error<E>>

where T: Iterator<Item = I>, I: Into<Self::Color>,
