Struct ws2812_esp32_rmt_driver::driver::Ws2812Esp32RmtDriver

pub struct Ws2812Esp32RmtDriver {
    pub grb_pixels: Option<Vec<u8>>,
    pub wait_tx_done: bool,
}

This is supported on crate feature unstable only.

Mock of Low-level WS2812 ESP32 RMT driver.

If the target vendor does not equals to “espressif”, this mock is used instead of genuine Low-level WS2812 ESP32 RMT driver.

Fields

grb_pixels: Option<Vec<u8>>

Pixel binary array to be written

wait_tx_done: bool

Whether wait for tx done (does not work on the mock!)

Implementations

impl Ws2812Esp32RmtDriver

pub fn new(
    _channel_num: u8,
    _gpio_num: u32
) -> Result<Self, Ws2812Esp32RmtDriverError>

This is supported on non-target_vendor="espressif" only.

Creates a mock of Ws2812Esp32RmtDriver. All arguments shall be ignored and always returns Ok(_).

pub fn write(
    &mut self,
    grb_pixels: &[u8]
) -> Result<(), Ws2812Esp32RmtDriverError>

This is supported on non-target_vendor="espressif" only.

Writes GRB pixel binary slice.

pub fn write_colors<I>(
    &mut self,
    iterator: I
) -> Result<(), Ws2812Esp32RmtDriverError> where
    I: IntoIterator<Item = LedPixelColorGrb24>, 

This is supported on non-target_vendor="espressif" only.

Writes GRB pixel binary with converting into LedPixelColorGrg24.
