Expand description

Serial receiver

Implementations

source

impl<USART, WORD> Rx<USART, WORD> where
USART: Instance,

source

pub fn listen(&mut self)

Start listening for an rx not empty interrupt event

Note, you will also have to enable the corresponding interrupt in the NVIC to start receiving events.

source

pub fn unlisten(&mut self)

Stop listening for the rx not empty interrupt event

source

pub fn listen_idle(&mut self)

Start listening for a line idle interrupt event

Note, you will also have to enable the corresponding interrupt in the NVIC to start receiving events.

source

pub fn unlisten_idle(&mut self)

Stop listening for the line idle interrupt event

source

pub fn is_idle(&self) -> bool

Return true if the line idle status is set

source

pub fn is_rx_not_empty(&self) -> bool

Return true if the rx register is not empty (and can be read)

source

pub fn clear_idle_interrupt(&self)

Clear idle line interrupt flag

Trait Implementations

source

impl<USART, PINS, WORD> AsMut<Rx<USART, WORD>> for Serial<USART, PINS, WORD>

source

fn as_mut(&mut self) -> &mut Rx<USART, WORD>

Performs the conversion.

source

impl<USART, PINS, WORD> AsRef<Rx<USART, WORD>> for Serial<USART, PINS, WORD>

source

fn as_ref(&self) -> &Rx<USART, WORD>

Performs the conversion.

source

impl<USART, WORD> ErrorType for Rx<USART, WORD>

impl<USART> PeriAddress for Rx<USART, u8> where
USART: Instance,

source

fn address(&self) -> u32

Returns the address to be used by the DMA stream.

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.

type Error = Error

Read error

source

fn read(&mut self) -> Result<u16, Self::Error>

Reads a single word from the serial interface

source

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.
