[−][src]Struct imxrt_hal::dma::Channel

pub struct Channel { /* fields omitted */ }

A DMA channel

DMA channels provide one-way transfers of data. They accept a source of data, and a destination of data. They copy data from the source to the destination. When the transfer is complete, a DMA channel signals completion by changing a value in a register, or triggering an interrupt.

DMA channels have very little public interface. They're best used when paired with a Peripheral or a Memcpy.

Implementations

impl Channel[src]

pub fn set_bandwidth_control(&mut self, bandwidth: Option<BandwidthControl>)[src]

Set the channel's bandwidth control

The bandwidth control will be used in any Memcpy or Peripheral DMA transfers.

  • None disables bandwidth control (default setting)
  • Some(bwc) sets the bandwidth control to bwc

pub fn channel(&self) -> usize[src]

Returns the DMA channel number

Channels are unique and numbered within the half-open range [0, 32).
