Trait sodaq_one::prelude::_embedded_hal_spi_FullDuplex

[−]

pub trait _embedded_hal_spi_FullDuplex<Word> {
    type Error;
    fn read(&mut self) -> Result<Word, Error<Self::Error>>;
    fn send(&mut self, word: Word) -> Result<(), Error<Self::Error>>;
}

Expand description

Full duplex (master mode)

Notes

It’s the task of the user of this interface to manage the slave select lines
Due to how full duplex SPI works each read call must be preceded by a send call.
Some SPIs can work with 8-bit and 16-bit words. You can overload this trait with different Word types to allow operation in both modes.

Associated Types

type Error

An enumeration of SPI errors

Required methods

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

Reads the word stored in the shift register

NOTE A word must be sent to the slave before attempting to call this method.

fn send(&mut self, word: Word) -> Result<(), Error<Self::Error>>

Sends a word to the slave

Implementors

source

impl<C> FullDuplex<<C as AnyConfig>::Word> for Spi<C, Duplex> where
    C: ValidConfig,
    <C as AnyConfig>::Word: PrimInt,
    <C as AnyConfig>::Word: AsPrimitive<u16>,
    u16: AsPrimitive<<C as AnyConfig>::Word>,

Implement spi::FullDuplex for Spi structs with AtomicSize

spi::FullDuplex is only implemented when the Spi struct has Duplex Capability. The Word size used in the implementation depends on the corresponding CharSize.
