Struct Channel 

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

DMAC channel.

Implementations

impl<'d> Channel<'d>

pub fn new<C: Instance, Int: InterruptType>( channel: Peri<'d, C>, irq: impl Binding<Int, DmacInterruptHandler<C>> + 'd, ) -> Self

Creates a new DMAC driver for a specific channel.

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

Reborrow the DMA Channel with a shorter lifetime.

pub fn write<W: Word>( &mut self, src: &[W], dest: *mut W, event: InterruptEvent, ) -> Transfer<'_>

Configures a DMAC transfer that reads from an address incremented by the specified InterruptEvent and writes to a fixed address. e.g. memory-to-peripheral.

Arguments

• src
• dest
• event

Returns

A future that will finish upon completion of the transfer.

pub fn read<W: Word>( &mut self, src: *const W, dest: &mut [W], event: InterruptEvent, ) -> Transfer<'_>

Configures a DMAC transfer that reads from a fixed address and writes to an address incremented by the specified InterruptEvent. e.g. peripheral-to-memory.

Arguments

• src
• dest
• event

Returns

A future that will finish upon completion of the transfer.

Trait Implementations

impl<'d> Drop for Channel<'d>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
