type Error = Error

Error type.

impl SpiBus for Spi

async fn read(&mut self, words: &mut [u8]) -> Result<(), Self::Error>

Read words from the slave.

async fn write(&mut self, data: &[u8]) -> Result<(), Self::Error>

Write words to the slave, ignoring all the incoming words.

async fn transfer( &mut self, rx: &mut [u8], tx: &[u8], ) -> Result<(), Self::Error>

Write and read simultaneously. write is written to the slave on MOSI and words received on MISO are stored in read.

async fn transfer_in_place( &mut self, words: &mut [u8], ) -> Result<(), Self::Error>

Write and read simultaneously. The contents of words are written to the slave, and the received words are stored into the same words buffer, overwriting it.

async fn flush(&mut self) -> Result<(), Self::Error>

Wait until all operations have completed and the bus is idle.
