How to use

    let spi_bus = Spi::new_txonly(
        p.SPI2,
        p.PB10,
        p.PC3,
        NoDma,
        NoDma,
        Hertz(8_000_000),
        embassy_stm32::spi::Config::default(),
    );
    let cs = Output::new(p.PC7, Level::Low, Speed::VeryHigh);
    let spi = ExclusiveDevice::new(spi_bus, cs, delay).unwrap();

    let dc = Output::new(p.PC9, Level::High, Speed::VeryHigh);
    let rst = Output::new(p.PA11, Level::Low, Speed::VeryHigh);
    let busy = Input::new(p.PG9, Pull::None);

    let di = EpdInterface::new(spi, dc, rst, busy);

    display.init(&mut delay);

    // draw display here

    display.display_frame();
