Struct Tx

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

Serial transmitter

Implementations

impl<USART: Instance> Tx<USART>

pub fn write_u16(&mut self, word: u16) -> Result<(), Infallible>

Writes 9-bit words to the UART/USART

If the UART/USART was configured with WordLength::Bits9, the 9 least significant bits will be transmitted and the other 7 bits will be ignored. Otherwise, the 8 least significant bits will be transmitted and the other 8 bits will be ignored.

pub fn write(&mut self, word: u8) -> Result<(), Infallible>

pub fn bwrite_all_u16(&mut self, buffer: &[u16]) -> Result<(), Infallible>

pub fn bwrite_all(&mut self, buffer: &[u8]) -> Result<(), Infallible>

pub fn flush(&mut self) -> Result<(), Infallible>

pub fn bflush(&mut self) -> Result<(), Infallible>

pub fn listen(&mut self)

Start listening for transmit interrupt event

pub fn unlisten(&mut self)

Stop listening for transmit interrupt event

pub fn is_tx_empty(&self) -> bool

Returns true if the tx register is empty (and can accept data)

pub fn is_tx_complete(&self) -> bool

impl Tx<USART1>

pub fn with_dma(self, channel: C4) -> TxDma1

impl Tx<USART2>

pub fn with_dma(self, channel: C7) -> TxDma2

impl Tx<USART3>

pub fn with_dma(self, channel: C2) -> TxDma3

Trait Implementations

impl<USART: Instance> Write for Tx<USART>

fn write_str(&mut self, s: &str) -> Result

Writes a string slice into this writer, returning whether the write succeeded.

fn write_char(&mut self, c: char) -> Result<(), Error>

Writes a char into this writer, returning whether the write succeeded.

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

Glue for usage of the write! macro with implementors of this trait.

impl<USART: Instance> Write<u16> for Tx<USART>

type Error = Infallible

The type of error that can occur when writing

fn bwrite_all(&mut self, buffer: &[u16]) -> Result<(), Self::Error>

Writes a slice, blocking until everything has been written

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

Block until the serial interface has sent all buffered words

impl<USART: Instance> Write<u8> for Tx<USART>

type Error = Infallible

The type of error that can occur when writing

fn bwrite_all(&mut self, buffer: &[u8]) -> Result<(), Self::Error>

Writes a slice, blocking until everything has been written

impl<USART: Instance> Write<u16> for Tx<USART>

type Error = Infallible

Write error

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

Writes a single word to the serial interface

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

Ensures that none of the previously written words are still buffered

type Error = Infallible

Write error

fn write(&mut self, word: u8) -> Result<(), Self::Error>

Writes a single word to the serial interface

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

Ensures that none of the previously written words are still buffered
