    );
    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);
