Struct Ws2812Esp32RmtDriverBuilder 

pub struct Ws2812Esp32RmtDriverBuilder<'d> { /* private fields */ }

Builder for Ws2812Esp32RmtDriver.

Examples

// WS2812B timing parameters.
const WS2812_T0H_NS: Duration = Duration::from_nanos(400);
const WS2812_T0L_NS: Duration = Duration::from_nanos(850);
const WS2812_T1H_NS: Duration = Duration::from_nanos(800);
const WS2812_T1L_NS: Duration = Duration::from_nanos(450);

let driver_config = TransmitConfig::new()
    .clock_divider(1); // Required parameter.
let tx_driver = TxRmtDriver::new(channel, led_pin, &driver_config).unwrap();
let driver = Ws2812Esp32RmtDriverBuilder::new_with_rmt_driver(tx_driver).unwrap()
   .encoder_duration(&WS2812_T0H_NS, &WS2812_T0L_NS, &WS2812_T1H_NS, &WS2812_T1L_NS).unwrap()
   .build().unwrap();

Implementations

impl<'d> Ws2812Esp32RmtDriverBuilder<'d>

pub fn new<C: RmtChannel>( channel: impl Peripheral<P = C> + 'd, pin: impl Peripheral<P = impl OutputPin> + 'd, ) -> Result<Self, Ws2812Esp32RmtDriverError>

Creates a new Ws2812Esp32RmtDriverBuilder.

pub fn new_with_rmt_driver( tx: TxRmtDriver<'d>, ) -> Result<Self, Ws2812Esp32RmtDriverError>

Creates a new Ws2812Esp32RmtDriverBuilder with TxRmtDriver.

pub fn encoder_duration( self, t0h: &Duration, t0l: &Duration, t1h: &Duration, t1l: &Duration, ) -> Result<Self, Ws2812Esp32RmtDriverError>

Sets the encoder duration times.

Arguments

• clock_hz - The clock frequency.
• t0h - T0H duration time (0 code, high voltage time)
• t0l - T0L duration time (0 code, low voltage time)
• t1h - T1H duration time (1 code, high voltage time)
• t1l - T1L duration time (1 code, low voltage time)

Errors

Returns an error if the encoder initialization failed.

pub fn build( self, ) -> Result<Ws2812Esp32RmtDriver<'d>, Ws2812Esp32RmtDriverError>

Builds the Ws2812Esp32RmtDriver.
