Struct Spdifrx

Source
pub struct Spdifrx<'d, T: Instance> { /* private fields */ }
Expand description

Ring-buffered SPDIFRX driver.

Data is read by DMAs and stored in a ring buffer.

Implementations§

Source§

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

Source

pub fn new( peri: impl Peripheral<P = T> + 'd, _irq: impl Binding<T::GlobalInterrupt, GlobalInterruptHandler<T>> + 'd, config: Config, spdifrx_in: impl Peripheral<P = impl InPin<T>> + 'd, data_dma: impl Peripheral<P = impl Channel + Dma<T>> + 'd, data_dma_buf: &'d mut [u32], ) -> Self

Create a new Spdifrx instance.

Source

pub fn start(&mut self)

Start the SPDIFRX driver.

Source

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

Read from the SPDIFRX data ring buffer.

SPDIFRX is always receiving data in the background. This function pops already-received data from the buffer.

If there’s less than data.len() data in the buffer, this waits until there is.
