Struct Channel

#[non_exhaustive]
pub struct Channel<'d, Dm, CH>
where
    Dm: DriverMode,
    CH: DmaChannel,
{
    pub rx: ChannelRx<'d, Dm, CH::Rx>,
    pub tx: ChannelTx<'d, Dm, CH::Tx>,
}

Available on crate feature unstable only.

DMA Channel

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

rx: ChannelRx<'d, Dm, CH::Rx>

RX half of the channel

tx: ChannelTx<'d, Dm, CH::Tx>

TX half of the channel

Implementations

impl<CH: DmaChannel, Dm: DriverMode> Channel<'_, Dm, CH>

pub fn runtime_ensure_compatible<P: DmaEligible>( &self, _peripheral: &PeripheralRef<'_, P>, )

Asserts that the channel is compatible with the given peripheral.

impl<'d, CH> Channel<'d, Blocking, CH>

where CH: DmaChannel,

pub fn new(channel: impl Peripheral<P = CH>) -> Self

Creates a new DMA channel driver.

Stability

This API is marked as unstable and is only available when the unstable crate feature is enabled. This comes with no stability guarantees, and could be changed or removed at any time.

pub fn set_interrupt_handler(&mut self, handler: InterruptHandler)

Sets the interrupt handler for RX and TX interrupts.

Interrupts are not enabled at the peripheral level here.

pub fn listen(&mut self, interrupts: impl Into<EnumSet<DmaInterrupt>>)

Listen for the given interrupts

pub fn unlisten(&mut self, interrupts: impl Into<EnumSet<DmaInterrupt>>)

Unlisten the given interrupts

pub fn interrupts(&mut self) -> EnumSet<DmaInterrupt>

Gets asserted interrupts

pub fn clear_interrupts(&mut self, interrupts: impl Into<EnumSet<DmaInterrupt>>)

Resets asserted interrupts

pub fn set_priority(&mut self, priority: DmaPriority)

Configure the channel priorities.

pub fn into_async(self) -> Channel<'d, Async, CH>

Converts a blocking channel to an async channel.

impl<'d, CH> Channel<'d, Async, CH>

where CH: DmaChannel,

pub fn into_blocking(self) -> Channel<'d, Blocking, CH>

Converts an async channel to a blocking channel.
