Struct Adf 

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

Ring-buffered ADF driver.

Implementations

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

pub fn new<D>( peri: Peri<'d, T>, irq: impl Binding<T::Interrupt, InterruptHandler<T>> + Binding<D::Interrupt, InterruptHandler<D>> + 'd, config: Config, cck: Peri<'d, impl CckPin<T>>, sdi: Peri<'d, impl SdiPin<T>>, dma: Peri<'d, D>, dma_buf: &'d mut [u32], ) -> Self

where D: RxDma<T, Flt0>,

Create a new ADF instance configured for PDM capture on filter 0.

cck drives the PDM bit clock and sdi receives the PDM data stream.

pub fn start(&mut self)

Start filter acquisition and DMA.

pub async fn read_raw(&mut self, words: &mut [u32]) -> Result<(), Error>

Read raw 32-bit DMA words from the filter output ring buffer.

pub fn kernel_clock_hz(&self) -> u32

Return the kernel clock frequency in Hz.

Trait Implementations

impl<'d, T: Instance> Drop for Adf<'d, T>

fn drop(&mut self)

Executes the destructor for this type.
