Struct AdcSampler

Source 
pub struct AdcSampler<'a, TIM, PPI0, PPI1, const MP: usize, const C: usize>
where
    [(); { _ }]:,
{ /* private fields */ }
Expand description

A sampler for the analog pins on an nRF MCU. This sampler can handle analog pins that may be multiplexed, or directly wired to the analog source. This can also be used to power an analog keyboard matrix.

Implementations§

Source§

impl<'a, TIM: Instance, PPI0: ConfigurableChannel, PPI1: ConfigurableChannel, const MP: usize, const C: usize> AdcSampler<'a, TIM, PPI0, PPI1, MP, C>
where [(); { _ }]:,

Source

pub fn new( idx_to_pin_type: [AnalogPinType<'a, MP>; C], configs: [ChannelConfig<'_>; C], timer: TIM, ppi_ch0: PPI0, ppi_ch1: PPI1, ) -> Self

Create a new instance of the ADC sampler.

Source

pub fn get_sample(&self, channel: usize, sub_channel: usize) -> Option<u16>

Obtain a sample from the ADC. The ch argument corresponds to the index of the analog pin you want to sample (which you provided in the Self::new() method). If the pin is multiplexed, the sub_ch argument is used to determine which multiplexer channel to sample from. Otherwise, the sub_ch argument is ignored.

Source§

type SampleType = u16

Type of samples generated by the ADC.
Source§

fn get_sample(&self, ch: usize, sub_ch: usize) -> Option<Self::SampleType>
