Trait Implementations

impl<'a> Spi<'a> for SpiDriver<'a>

fn initialize(&mut self, callback: impl FnMut(Event) + 'a) -> Result<(), i32>

Initializes the SPI peripheral.

fn uninitialize(&mut self) -> Result<(), i32>

De-initializes the SPI peripheral.

fn configure(&mut self, config: &Config) -> Result<(), i32>

Configures the SPI peripheral.

fn send(&mut self, data: &[u8]) -> Result<(), i32>

Transmits data over the SPI bus.

fn receive(&mut self, data: &mut [u8]) -> Result<(), i32>

Receives data from the SPI bus.

fn transfer(&mut self, data_out: &[u8], data_in: &mut [u8]) -> Result<(), i32>

Simultaneously sends and receives data.

fn get_data_count(&self) -> u32

Gets the number of bytes transferred in the last transaction.

fn get_status(&self) -> Status

Gets the current status of the SPI peripheral.

fn control_slave_select(&mut self, active: bool) -> Result<(), i32>
