Module atmega_hal::adc

Analog-to-Digital Converter

Example

Complete example source code can be found in the repository: atmega2560-adc.rs

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

let mut adc = Adc::new(dp.ADC, Default::default());

let channels: [atmega_hal::adc::Channel; 4] = [
    pins.pf0.into_analog_input(&mut adc).into_channel(),
    pins.pf1.into_analog_input(&mut adc).into_channel(),
    pins.pf2.into_analog_input(&mut adc).into_channel(),
    pins.pf3.into_analog_input(&mut adc).into_channel(),
];

for (index, channel) in channels.iter().enumerate() {
    let value = adc.read_blocking(channel);
    ufmt::uwrite!(&mut serial, "CH{}: {} ", index, value).unwrap();
}
