Trait atsamd_hal::prelude::_embedded_hal_serial_Read

pub trait _embedded_hal_serial_Read<Word> {
    type Error;

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

Read half of a serial interface

Some serial interfaces support different data sizes (8 bits, 9 bits, etc.); This can be encoded in this trait via the Word type parameter.

Required Associated Types

type Error

Read error

Required Methods

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

Reads a single word from the serial interface

Implementors

impl<C, D> Read<<C as AnyConfig>::Word> for Uart<C, D>where
    C: ValidConfig,
    D: Receive,
    DataReg: AsPrimitive<C::Word>,

type Error = Error

impl<P, L> Read<<L as Length>::Word> for Spi<Config<P, Slave, L>, Rx>where
    Config<P, Slave, L>: ValidConfig,
    P: ValidPads,
    L: Length,
    L::Word: PrimInt,
    u32: AsPrimitive<L::Word>,

Implement serial::Read for Rx Spi structs in Slave OpMode

serial::Read is only implemented for Spi structs with Rx Capability. In Slave OpMode, Read does not have to initiate transactions, so it does not have to store any internal state. It only has to wait on RXC.

type Error = Error

impl<P, M, L> Read<<L as Length>::Word> for Spi<Config<P, M, L>, Rx>where
    Config<P, M, L>: ValidConfig,
    P: ValidPads,
    M: MasterMode,
    L: Length,
    L::Word: PrimInt,
    u32: AsPrimitive<L::Word>,

Implement serial::Read for Rx Spi structs in a MasterMode

serial::Read is only implemented for Spi structs with Rx Capability. In a MasterMode, Read has to initiate transactions, so it keeps track of the transaction state. If a transaction is in progress, it will wait on RXC. If not, it will wait on DRE, and then send 0.
