dst_peripheral: u8

Destination peripheral select (0-15).

flow_control: FlowControl

Flow control mode.

src_width: TransferWidth

Source transfer width.

dst_width: TransferWidth

Destination transfer width.

src_burst: BurstSize

Source burst size.

dst_burst: BurstSize

Destination burst size.

src_inc: bool

Increment source address after each beat.

dst_inc: bool

Increment destination address after each beat.

Implementations

impl DmaChannelConfig

pub fn mem_to_peripheral(self, peri: DmaPeripheral) -> Self

Configure this channel for a memory → peripheral transfer to peri: sets MemToPeripheral flow control, the destination handshaking ID, and holds the destination address fixed (a peripheral data register).

pub fn peripheral_to_mem(self, peri: DmaPeripheral) -> Self

Configure this channel for a peripheral → memory transfer from peri: sets PeripheralToMem flow control, the source handshaking ID, and holds the source address fixed (a peripheral data register).

Performs copy-assignment from source.

impl Copy for DmaChannelConfig

impl Debug for DmaChannelConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result
