Struct esp32_hal::i2s::I2sWriteDmaTransfer

pub struct I2sWriteDmaTransfer<T, P, TX, BUFFER>where
    T: RegisterAccess,
    P: I2sTxPins,
    TX: Tx,{ /* private fields */ }

An in-progress DMA write transfer.

Implementations

impl<'d, T, P, TX, BUFFER> I2sWriteDmaTransfer<T, P, TX, BUFFER>where
    T: RegisterAccess,
    P: I2sTxPins,
    TX: Tx,

pub fn available(&mut self) -> usize

Amount of bytes which can be pushed. Only useful for circular DMA transfers

pub fn push(&mut self, data: &[u8]) -> Result<usize, Error>

Push bytes into the DMA buffer. Only useful for circular DMA transfers
