pub struct Adc<'d, T: Instance, M: Mode> { /* private fields */ }

ADC (Analog to Digial Converter) Driver.

Implementations

impl<'d, T: Instance> Adc<'d, T, Blocking>

pub fn new_blocking(peri: Peri<'d, T>, config: Config) -> Self

A new blocking ADC driver instance.

impl<'d, T: Instance> Adc<'d, T, Async>

pub fn new_async( peri: Peri<'d, T>, config: Config, _irqs: impl Binding<T::Interrupt, InterruptHandler<T>> + 'd, ) -> Self

A new asynchronous ADC driver instance.

impl<'d, T: Instance, M: Mode> Adc<'d, T, M>

pub fn blocking_read(&mut self, channel: &Peri<'d, impl AdcChannel<T>>) -> u16

Read one ADC channel in blocking mode using the config provided at initialization.

impl<'d, T: Instance> Adc<'d, T, Async>

pub const MAX_SEQUENCE_LEN: usize = 4usize

Maximum length allowed for Self::read_sequence.

pub async fn read_channel( &mut self, channel: &Peri<'d, impl AdcChannel<T>>, ) -> u16

Read one ADC channel asynchronously using the config provided at initialization.

pub async fn read_sequence<'a>( &mut self, sequence: impl ExactSizeIterator<Item = (&'a Peri<'d, AnyAdcChannel<T>>, Vrsel)>, readings: &mut [u16], )

where 'd: 'a,

Read one or multiple ADC channels using the Vrsel provided per channel.

sequence iterator and readings must have the same length.

Example

use embassy_mspm0::adc::{Adc, AdcChannel, Vrsel};

let mut adc = Adc::new_async(p.ADC0, adc_config, Irqs);
let sequence = [(&p.PA22.into(), Vrsel::VddaVssa), (&p.PA20.into(), Vrsel::VddaVssa)];
let mut readings = [0u16; 2];

adc.read_sequence(sequence.into_iter(), &mut readings).await;
defmt::info!("Measurements: {}", readings);
