Trait stm32f4xx_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<USART, PINS, WORD> Read<WORD> for Serial<USART, PINS, WORD> where
    USART: Instance,
    Rx<USART, WORD>: Read<WORD, Error = Error>, 

type Error = ErrorKind

impl<USART: Instance> Read<u8> for Rx<USART, u8>

type Error = ErrorKind

impl<USART: Instance> Read<u16> for Rx<USART, u16>

Reads 9-bit words from the UART/USART

If the UART/USART was configured with WordLength::DataBits9, the returned value will contain 9 received data bits and all other bits set to zero. Otherwise, the returned value will contain 8 received data bits and all other bits set to zero.
