Struct imxrt_hal::dma::Unclocked

pub struct Unclocked(_);

Unclocked, uninitialized DMA channels

Use clock() to initialize and acquire all DMA channels

let mut peripherals = imxrt_hal::Peripherals::take().unwrap();

let mut dma_channels = peripherals.dma.clock(&mut peripherals.ccm.handle);
let channel_27 = dma_channels[27].take().unwrap();
let channel_0 = dma_channels[0].take().unwrap();

Implementations

impl Unclocked

pub fn clock(self, ccm: &mut Handle) -> [Option<Channel>; 32]

Enable the clocks for the DMA peripheral

The return is 32 channels, each being initialized as Some(Channel). Users may take channels as needed. The index in the array maps to the DMA channel number.
