Struct rp2040_hal :: dma :: double_buffer :: Config Copy item path

impl<CH1, CH2, FROM, TO, WORD> Config<CH1, CH2, FROM, TO>
where CH1: SingleChannel, CH2: SingleChannel, FROM: ReadTarget<ReceivedWord = WORD>, TO: WriteTarget<TransmittedWord = WORD>,

pub fn new(ch: (CH1, CH2), from: FROM, to: TO) -> Config<CH1, CH2, FROM, TO>

Create a new configuration for double-buffered DMA transfer

pub fn pace(&mut self, pace: Pace)

Sets the (preferred) pace for the DMA transfers.

Usually, the code will automatically configure the correct pace, but peripheral-to-peripheral transfers require the user to manually select whether the source or the sink shall be queried for the pace signal.

pub fn bswap(&mut self, bswap: bool)

Enable/disable byteswapping for the DMA transfers, default value is false.

For byte data, this has no effect. For halfword data, the two bytes of each halfword are swapped. For word data, the four bytes of each word are swapped to reverse order.

This is a convenient way to change the (half-)words’ byte endianness on the fly.

pub fn start(self) -> Transfer<CH1, CH2, FROM, TO, ()>

Start the DMA transfer
