Struct Transfer 

pub struct Transfer<State, I: Instance> { /* private fields */ }

An SPI/DMA transfer

Since the SPI peripheral is capable of sending and receiving at the same time, using the same buffer, it needs this bespoke Transfer struct, which wraps and manages two dma::Transfer structs under the hood.

Implementations

impl<I> Transfer<Ready, I>

where I: Instance,

pub fn start(self) -> Transfer<Started, I>

Start the transfer

Starts both DMA transfers that are part of this SPI transfer.

impl<I> Transfer<Started, I>

where I: Instance,

pub fn wait( self, ) -> (SPI<I, Enabled<Master>>, &'static mut [u8], Channel<I::RxChannel, Enabled>, Channel<I::TxChannel, Enabled>)

Wait for the transfer to finish

Waits until both underlying DMA transfers have finished.
