Struct Ws2812BlockingWriter

pub struct Ws2812BlockingWriter<SPI> { /* private fields */ }

Wraps a SPI Writer to represent a WS2821 LED array.

Examples:

use ws2812_blocking_spi::Ws2812BlockingWriter;

use embedded_hal::blocking::spi::Write;
use smart_leds_trait::{RGB8, SmartLedsWrite};

//
// Displays 3 LEDs: red, green and blue
//
fn show<SPI: Write<u8>>(spi: SPI) {
   let mut leds = Ws2812BlockingWriter::new(spi);

   let mut data = [RGB8::default(); 3];

   data[0] = [0xFF_u8, 0_u8, 0_u8].into();  // Full RED
   data[1] = [0_u8, 0xFF_u8, 0_u8].into();  // Full GREEN
   data[2] = [0_u8, 0_u8, 0xFF_u8].into();  // Full BLUE

   leds.write(data.iter().cloned());
}
