Struct Rx

pub struct Rx<USART> { /* private fields */ }

Serial receiver

Implementations

impl<USART: Instance> Rx<USART>

pub fn read_u16(&mut self) -> Result<u16, Error>

Reads 9-bit words from the UART/USART

If the UART/USART was configured with WordLength::Bits9, 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.

pub fn read(&mut self) -> Result<u8, Error>

pub fn listen(&mut self)

Start listening for receive interrupt event

pub fn unlisten(&mut self)

Stop listening for receive interrupt event

pub fn listen_idle(&mut self)

Start listening for idle interrupt event

pub fn unlisten_idle(&mut self)

Stop listening for idle interrupt event

pub fn is_idle(&self) -> bool

Returns true if the line idle status is set

pub fn is_rx_not_empty(&self) -> bool

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

pub fn clear_idle_interrupt(&self)

Clear idle line interrupt flag

impl Rx<USART2>

pub fn with_dma(self, channel: C6) -> RxDma2
