Struct DoubleBufferedTransfer 

pub struct DoubleBufferedTransfer<S> { /* private fields */ }

Double-buffered DMA transfer

Implementations

impl<S> DoubleBufferedTransfer<S>

pub fn new<'s>(stream: S3) -> Self

Construct a new DMA transfer state, returned by start_transfer which configures and enables the stream before.

pub fn writable(&mut self) -> bool

Has the back buffer been sent?

As this is used for polling, the function updates the sent status of the front buffer.

pub fn write<'s>(&mut self, source: &'s [S]) -> Result<(), ()>

Update the back buffer.

impl<'s, S> DmaStreamTransfer<(&'s [S], &'s [S]), S, DoubleBufferedTransfer<S>> for S3

fn start_transfer<CHANNEL: DmaChannel>( self, (source0, source1): (&'s [S], &'s [S]), target: &mut S, ) -> DoubleBufferedTransfer<S>

Configure, enable, and return a double-buffered DMA transfer.

impl<S> Transfer<S3> for DoubleBufferedTransfer<S>

fn is_complete(&self) -> bool

Transfer is complete?

fn has_error(&self) -> bool

Transfer has error?

fn reset(self) -> S3

Reset after a transfer

fn wait(self) -> Result<STREAM, STREAM>

Wait until transfer is either complete or has error.
