pub struct Spidev(pub Spidev);

Newtype around spidev::Spidev that implements the embedded-hal traits

Tuple Fields

0: Spidev

Implementations

impl Spidev

pub fn open<P>(path: P) -> Result<Spidev, Error> where
    P: AsRef<Path>, 

See spidev::Spidev::open for details.

Methods from Deref<Target = Spidev>

pub fn inner(&self) -> &File

Get a reference to the underlying File object

pub fn configure(&mut self, options: &SpidevOptions) -> Result<(), Error>

Write the provided configuration to this device

pub fn transfer(
    &self,
    transfer: &mut spi_ioc_transfer<'_, '_>
) -> Result<(), Error>

Perform a single transfer

pub fn transfer_multiple(
    &self,
    transfers: &mut [spi_ioc_transfer<'_, '_>]
) -> Result<(), Error>

Perform multiple transfers in a single system call to the kernel

Chaining together multiple requests like this can reduce latency and be used for conveniently and efficient implementing some protocols without extra round trips back to userspace.

Trait Implementations

impl Deref for Spidev

type Target = Spidev

The resulting type after dereferencing.

pub fn deref(&self) -> &<Spidev as Deref>::Target

Dereferences the value.

impl DerefMut for Spidev

pub fn deref_mut(&mut self) -> &mut <Spidev as Deref>::Target

Mutably dereferences the value.

impl Transactional<u8> for Spidev

Transactional implementation batches SPI operations into a single transaction

type Error = Error

Associated error type

pub fn exec(
    &mut self,
    operations: &mut [Operation<'a, u8>]
) -> Result<(), <Spidev as Transactional<u8>>::Error>

Execute the provided transactions

impl Transfer<u8> for Spidev

type Error = Error

Error type

pub fn transfer(&mut self, buffer: &'b mut [u8]) -> Result<(), Error>

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

impl Write<u8> for Spidev

type Error = Error

Error type

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

Writes words to the slave, ignoring all the incoming words
