Struct Reader

Source
pub struct Reader<'s, 'd, W: Word>(/* private fields */);
Expand description

I2S driver reader. Useful for moving read functionality across tasks.

Implementations§

Source§

impl<'s, 'd, W: Word> Reader<'s, 'd, W>

Source

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

Read data from the I2S ringbuffer. SAI 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.

Source

pub fn reset(&mut self)

Reset the ring buffer to its initial state. Can be used to prevent overrun. The ringbuffer will always auto-reset on Overrun in any case.
