Struct Spi

pub struct Spi<T>(/* private fields */);

Interface to a SPI instance.

Implementations

impl<T> Spi<T>

where T: Instance,

pub fn new(spi: T, pins: Pins, frequency: FREQUENCY_A, mode: Mode) -> Spi<T>

pub fn free(self) -> T

Return the raw interface to the underlying SPI peripheral.

Trait Implementations

impl<T> ErrorType for Spi<T>

type Error = Infallible

Error type.

impl<T> SpiBus for Spi<T>

where T: Instance,

fn read(&mut self, words: &mut [u8]) -> Result<(), <Spi<T> as ErrorType>::Error>

Read words from the slave.

fn write(&mut self, words: &[u8]) -> Result<(), <Spi<T> as ErrorType>::Error>

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

fn transfer( &mut self, read: &mut [u8], write: &[u8], ) -> Result<(), <Spi<T> as ErrorType>::Error>

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

fn transfer_in_place( &mut self, words: &mut [u8], ) -> Result<(), <Spi<T> as ErrorType>::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.

fn flush(&mut self) -> Result<(), <Spi<T> as ErrorType>::Error>

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