Struct Channel 

pub struct Channel<const N: u8> { /* private fields */ }

One DMA channel, identified by its number at the type level.

Implementations

impl<const N: u8> Channel<N>

where Channel<N>: ChannelOps,

pub fn write_to<P: DmaDst<N>>( self, periph: P, buf: &'static [P::Word], prio: Prio, ) -> Transfer<N, P, &'static [P::Word]>

Starts a memory-to-peripheral transfer, moving buf into periph.

All three are taken by value and come back from Transfer::wait. The transfer width follows from the peripheral’s word type, so buf must match it.

pub fn read_from<P: DmaSrc<N>>( self, periph: P, buf: &'static mut [P::Word], prio: Prio, ) -> Transfer<N, P, &'static mut [P::Word]>

Starts a peripheral-to-memory transfer, filling buf from periph.

All three are taken by value and come back from Transfer::wait, so buf cannot be read before the transfer completes. The transfer width follows from the peripheral’s word type, so buf must match it.
