Struct Mem2Mem 

pub struct Mem2Mem<'d, Dm>
where
    Dm: DriverMode,
{
    pub rx: Mem2MemRx<'d, Dm>,
    pub tx: Mem2MemTx<'d, Dm>,
}

DMA Memory to Memory pseudo-Peripheral

This is a pseudo-peripheral that allows for memory to memory transfers. It is not a real peripheral, but a way to use the DMA engine for memory to memory transfers.

Fields

rx: Mem2MemRx<'d, Dm>

RX Half

tx: Mem2MemTx<'d, Dm>

TX Half

Implementations

impl<'d> Mem2Mem<'d, Blocking>

pub fn new( channel: impl DmaChannelConvert<AnyGdmaChannel<'d>>, peripheral: impl DmaEligible, ) -> Self

Create a new Mem2Mem instance.

pub unsafe fn new_unsafe( channel: impl DmaChannelConvert<AnyGdmaChannel<'d>>, peripheral: DmaPeripheral, ) -> Self

Create a new Mem2Mem instance.

Safety

You must ensure that you’re not using DMA for the same peripheral and that you’re the only one using the DmaPeripheral.

pub fn with_descriptors( self, rx_descriptors: &'static mut [DmaDescriptor], tx_descriptors: &'static mut [DmaDescriptor], config: BurstConfig, ) -> Result<SimpleMem2Mem<'d, Blocking>, DmaError>

Shortcut to create a SimpleMem2Mem

pub fn into_async(self) -> Mem2Mem<'d, Async>

Convert Mem2Mem to an async Mem2Mem.
