Struct RgbwPioWs2812 

pub struct RgbwPioWs2812<'d, P: Instance, const S: usize, ORDER>
where
    ORDER: RgbwColorOrder,
{ /* private fields */ }

Pio backed RGBW ws2812 driver This version is intended for ws2812 leds with 4 addressable lights Const N is the number of ws2812 leds attached to this pin

Implementations

impl<'d, P: Instance, const S: usize> RgbwPioWs2812<'d, P, S, Grbw>

pub fn new<D: ChannelInstance>( pio: &mut Common<'d, P>, sm: StateMachine<'d, P, S>, pin: Peri<'d, impl PioPin>, dma: Peri<'d, D>, irq: impl Binding<D::Interrupt, InterruptHandler<D>> + 'd, program: &PioWs2812Program<'d, P>, ) -> Self

Configure a pio state machine to use the loaded ws2812 program. Uses the default GRBW color order

impl<'d, P: Instance, const S: usize, ORDER> RgbwPioWs2812<'d, P, S, ORDER>

where ORDER: RgbwColorOrder,

pub fn with_color_order<D: ChannelInstance>( pio: &mut Common<'d, P>, sm: StateMachine<'d, P, S>, pin: Peri<'d, impl PioPin>, dma: Peri<'d, D>, irq: impl Binding<D::Interrupt, InterruptHandler<D>> + 'd, program: &PioWs2812Program<'d, P>, ) -> Self

Configure a pio state machine to use the loaded ws2812 program. Uses the specified color order

pub async fn write_slice<const N: usize>(&mut self, colors: &[RGBW<u8>; N])

Write a buffer of [smart_leds::RGBW] to the ws2812 string
