Struct Channel 

pub struct Channel<'d> { /* private fields */ }

DMA channel driver.

Implementations

impl<'d> Channel<'d>

pub fn new<T: ChannelInstance>( _ch: Peri<'d, T>, _irq: impl Binding<T::Interrupt, InterruptHandler<T>> + 'd, ) -> Self

Create a new DMA channel driver.

pub fn reborrow(&mut self) -> Channel<'_>

Reborrow the channel, allowing it to be used in multiple places.

pub unsafe fn read<'a, W: Word>( &'a mut self, from: *const W, to: *mut [W], dreq: TreqSel, ) -> Transfer<'a>

DMA read from a peripheral to memory.

SAFETY: Slice must point to a valid location reachable by DMA.

pub unsafe fn write<'a, W: Word>( &'a mut self, from: *const [W], to: *mut W, dreq: TreqSel, ) -> Transfer<'a>

DMA write from memory to a peripheral.

SAFETY: Slice must point to a valid location reachable by DMA.

pub unsafe fn write_repeated<'a, W: Word>( &'a mut self, count: usize, to: *mut W, dreq: TreqSel, ) -> Transfer<'a>

DMA repeated write of the same value from memory to a peripheral.

SAFETY: to must point to a valid location reachable by DMA.

pub unsafe fn copy<'a, W: Word>( &'a mut self, from: &[W], to: &mut [W], ) -> Transfer<'a>

DMA copy between memory regions.

SAFETY: Slices must point to locations reachable by DMA.
