Trait Implementations

impl ErrorType for Qspi

type Error = SpiError

Error type.

impl Peripheral for Qspi

fn take() -> Option<Self>

unsafe fn steal() -> Self

impl SetConfig for Qspi

type Config = SpiConfig

The configuration type used by this driver.

type ConfigError = ()

The error type that can occur if set_config fails.

fn set_config(&mut self, config: &Self::Config) -> Result<(), ()>

Set the configuration of the driver.

impl SpiBus for Qspi

When buffers are 4 byte aligned, QSPI can read and write 32-bit words. Otherwise, the 8-bit interface is used.

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

Read words from the slave.

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

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

fn transfer(&mut self, read: &mut [u8], write: &[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.

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.

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

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

impl SpiBus for Qspi

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

Read words from the slave.

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

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

async fn transfer( &mut self, read: &mut [u8], write: &[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.
