Trait st7735_async_low::spi::WriteU8[−][src]

pub trait WriteU8<'a> {
    type WriteU8Done: 'a + Future<Output = ()>;
    fn write_u8(&'a mut self, data: u8) -> Self::WriteU8Done;
}

Defines how a single u8 is written with the SCK and SDA pins.

Common MCUs’ SPI peripheral can be used, with CPOL=1, CPHA=1 and MSB-first. Notice the timing requirement from ST7735’s datasheet. Most important ones:

  • SCK low duration and high durations are at least 15ns long.
  • SCK period is at least 66ns long.
