Implementations

impl Spidev

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

See spidev::Spidev::open for details.

Methods from Deref<Target = Spidev>

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.
