Struct Adc

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

Analog to Digital driver.

Implementations

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

pub fn new( adc: impl Peripheral<P = T> + 'd, sample_time: SampleTime, resolution: Resolution, ) -> Self

Create a new ADC driver.

pub fn enable_vrefint(&self) -> VrefInt

Enable reading the voltage reference internal channel.

pub fn enable_temperature(&self) -> Temperature

Enable reading the temperature internal channel.

pub fn set_sample_time_all_channels(&mut self, sample_time: SampleTime)

Set the ADC sample time. Shall only be called when ADC is not converting.

pub fn set_resolution(&mut self, resolution: Resolution)

Set the ADC resolution.

pub fn blocking_read(&mut self, channel: &mut impl AdcChannel<T>) -> u16

pub async fn read_in_hw_order( &mut self, rx_dma: &mut impl RxDma<T>, hw_channel_selection: u32, scandir: Scandir, readings: &mut [u16], )

Read one or multiple ADC channels using DMA in hardware order. Readings will be ordered based on hardware ADC channel number and scandir setting. Readings won’t be in the same order as in the set!

In STM32C0, channels bigger than 14 cannot be read using sequencer, so you have to use either blocking reads or use the mechanism to read in HW order (CHSELRMOD=0). TODO(chudsaviet): externalize generic code and merge with read().

pub async fn read( &mut self, rx_dma: &mut impl RxDma<T>, channel_sequence: impl ExactSizeIterator<Item = &mut AnyAdcChannel<T>>, readings: &mut [u16], )
