Struct Adc 

pub struct Adc<'d, ADC, Dm: DriverMode> { /* private fields */ }

Available on crate feature unstable only.

Analog-to-Digital Converter peripheral driver.

Implementations

impl<'d, ADCX> Adc<'d, ADCX, Blocking>

where ADCX: RegisterAccess + 'd,

pub fn new(adc_instance: ADCX, _config: AdcConfig<ADCX>) -> Self

Configures a given ADC instance using the provided configuration, and initializes the ADC for use.

The ESP32-S31 SAR ADC has a single attenuation setting, so the attenuation given per pin has no effect.

pub fn into_async(self) -> Adc<'d, ADCX, Async>

Reconfigures the ADC driver to operate in asynchronous mode.

pub fn read_blocking<PIN, CS>(&mut self, pin: &mut AdcPin<PIN, ADCX, CS>) -> u16

where PIN: AdcChannel, CS: AdcCalScheme<ADCX>,

Starts and waits for a conversion on the specified pin and returns the result.

The result is in the range 0..=FULL_SCALE, and an input tied to ground reads about ZERO_DIFF_CODE.

pub fn read_oneshot<PIN, CS>( &mut self, pin: &mut AdcPin<PIN, ADCX, CS>, ) -> Result<u16, ()>

where PIN: AdcChannel, CS: AdcCalScheme<ADCX>,

Requests that the ADC begin a conversion on the specified pin.

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

The result is in the range 0..=FULL_SCALE, and an input tied to ground reads about ZERO_DIFF_CODE.

impl<'d, ADCX> Adc<'d, ADCX, Async>

where ADCX: RegisterAccess + 'd,

pub fn into_blocking(self) -> Adc<'d, ADCX, Blocking>

Reconfigures the ADC driver to operate in Blocking mode.

pub async fn read_oneshot<PIN, CS>( &mut self, pin: &mut AdcPin<PIN, ADCX, CS>, ) -> u16

where ADCX: Instance, PIN: AdcChannel, CS: AdcCalScheme<ADCX>,

Starts a conversion on the specified pin and waits for the result.

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

The result is in the range 0..=FULL_SCALE, and an input tied to ground reads about ZERO_DIFF_CODE.

Trait Implementations

impl<ADCX> InterruptConfigurable for Adc<'_, ADCX, Blocking>

fn set_interrupt_handler(&mut self, handler: InterruptHandler)

Registers an interrupt handler for the peripheral on the current core.
