DMA channel driver

Implementations

impl<'d> Channel<'d>

pub unsafe fn transfer<'a, MW: Word, PW: Word>( &'a mut self, request: Request, buf: *const [MW], dest_addr: *mut PW, options: TransferOptions, ) -> Transfer<'a>

Create a memory DMA transfer (memory to memory), using raw pointers.

pub unsafe fn transfer_raw<'a, MW: Word, PW: Word>( &'a mut self, request: Request, src_addr: *const MW, src_size: usize, dest_addr: *mut PW, options: TransferOptions, ) -> Transfer<'a>

Create a memory DMA transfer (memory to memory), using raw pointers.

pub unsafe fn read<'a, W: Word>( &'a mut self, request: Request, peri_addr: *mut W, buf: &'a mut [W], options: TransferOptions, ) -> Transfer<'a>

Create a read DMA transfer (peripheral to memory).

pub unsafe fn read_raw<'a, MW: Word, PW: Word>( &'a mut self, request: Request, peri_addr: *mut PW, buf: *mut [MW], options: TransferOptions, ) -> Transfer<'a>

Create a read DMA transfer (peripheral to memory), using raw pointers.

pub unsafe fn write<'a, MW: Word, PW: Word>( &'a mut self, request: Request, buf: &'a [MW], peri_addr: *mut PW, options: TransferOptions, ) -> Transfer<'a>

Create a write DMA transfer (memory to peripheral).

pub unsafe fn write_raw<'a, MW: Word, PW: Word>( &'a mut self, request: Request, buf: *const [MW], peri_addr: *mut PW, options: TransferOptions, ) -> Transfer<'a>

Create a write DMA transfer (memory to peripheral), using raw pointers.

pub unsafe fn write_repeated<'a, W: Word>( &'a mut self, request: Request, repeated: &'a W, count: usize, peri_addr: *mut W, options: TransferOptions, ) -> Transfer<'a>

Create a write DMA transfer (memory to peripheral), writing the same value repeatedly.

impl<'d> Channel<'d>

pub fn new<T: ChannelInstance>( _ch: Peri<'d, T>, _irq: impl Binding<T::Interrupt, InterruptHandler<T>> + 'd, ) -> Self

Create a new DMA channel driver.

pub fn reborrow(&mut self) -> Channel<'_>

Reborrow the channel, allowing it to be used in multiple places.
