Available on crate feature unstable only.
Expand description

Analog-to-Digital Converter peripheral driver.

Implementations§

Source§

impl<'d, ADCI> Adc<'d, ADCI, Blocking>
where ADCI: RegisterAccess,

Source

pub fn new( adc_instance: impl Peripheral<P = ADCI> + 'd, config: AdcConfig<ADCI>, ) -> Self

Configure a given ADC instance using the provided configuration, and initialize the ADC for use

Source

pub fn read_blocking<PIN, CS>(&mut self, pin: &mut AdcPin<PIN, ADCI, CS>) -> u16
where PIN: AdcChannel, CS: AdcCalScheme<ADCI>,

Start and wait for a conversion on the specified pin and return the result

Source

pub fn read_oneshot<PIN, CS>( &mut self, pin: &mut AdcPin<PIN, ADCI, CS>, ) -> Result<u16, ()>
where PIN: AdcChannel, CS: AdcCalScheme<ADCI>,

Request that the ADC begin a conversion on the specified pin

This method takes an AdcPin reference, as it is expected that the ADC will be able to sample whatever channel underlies the pin.
