Struct SpiBus 

pub struct SpiBus { /* private fields */ }

Implementations

impl SpiBus

pub fn new(bus: SpiBusId, config: &Config) -> Self

Initializes a new SPI bus with the given configuration.

Arguments

• bus - The identifier for the SPI bus.
• config - A reference to the configuration parameters for the SPI bus.

Returns

A new SpiBus instance configured according to the provided parameters.

pub fn to_device<NSS: OutputPin>(self, nss: NSS) -> SpiDevice<NSS>

Converts the SPI bus into a SPI device by associating it with a chip select pin.

Arguments

• nss - The chip select pin configured as an output.

Returns

A SpiDevice instance ready to communicate with a specific device.

Trait Implementations

impl Clone for SpiBus

fn clone(&self) -> SpiBus

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SpiBus

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for SpiBus

fn drop(&mut self)

Executes the destructor for this type.

impl ErrorType for SpiBus

type Error = Error

Error type.

impl SpiBus for SpiBus

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

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

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.
