Module attiny_hal::spi

SPI

Example

For full source code, please refer to the ATmega SPI example: atmega2560-spi-feedback.rs

let dp = attiny_hal::Peripherals::take().unwrap();
let pins = attiny_hal::pins!(dp);

let (mut spi, mut cs) = spi::Spi::new(
    dp.SPI,
    pins.pa4.into_output(),
    pins.pa6.into_output(),
    pins.pa5.into_pull_up_input(),
    pins.pa3.into_output(),
    spi::Settings::default(),
);

let data_out = b"Hello World!";
let mut data_in = [0u8; 12];

cs.set_low().unwrap();
spi.transfer(&mut data_in, data_out).unwrap();
cs.set_high().unwrap();

ufmt::uwriteln!(&mut serial, "data: {:?}", data_in).unwrap();
