Struct embassy_stm32::usart::UartTx

pub struct UartTx<'d, M: Mode> { /* private fields */ }

Tx-only UART Driver.

Can be obtained from Uart::split, or can be constructed independently, if you do not need the receiving half of the driver.

Implementations

impl<'d> UartTx<'d, Async>

pub fn new<T: Instance>( peri: impl Peripheral<P = T> + 'd, tx: impl Peripheral<P = impl TxPin<T>> + 'd, tx_dma: impl Peripheral<P = impl TxDma<T>> + 'd, config: Config, ) -> Result<Self, ConfigError>

Useful if you only want Uart Tx. It saves 1 pin and consumes a little less power.

pub fn new_with_cts<T: Instance>( peri: impl Peripheral<P = T> + 'd, tx: impl Peripheral<P = impl TxPin<T>> + 'd, cts: impl Peripheral<P = impl CtsPin<T>> + 'd, tx_dma: impl Peripheral<P = impl TxDma<T>> + 'd, config: Config, ) -> Result<Self, ConfigError>

Create a new tx-only UART with a clear-to-send pin

pub async fn write(&mut self, buffer: &[u8]) -> Result<(), Error>

Initiate an asynchronous UART write

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

Wait until transmission complete

impl<'d> UartTx<'d, Blocking>

pub fn new_blocking<T: Instance>( peri: impl Peripheral<P = T> + 'd, tx: impl Peripheral<P = impl TxPin<T>> + 'd, config: Config, ) -> Result<Self, ConfigError>

Create a new blocking tx-only UART with no hardware flow control.

Useful if you only want Uart Tx. It saves 1 pin and consumes a little less power.

pub fn new_blocking_with_cts<T: Instance>( peri: impl Peripheral<P = T> + 'd, tx: impl Peripheral<P = impl TxPin<T>> + 'd, cts: impl Peripheral<P = impl CtsPin<T>> + 'd, config: Config, ) -> Result<Self, ConfigError>

Create a new blocking tx-only UART with a clear-to-send pin

impl<'d, M: Mode> UartTx<'d, M>

pub fn set_config(&mut self, config: &Config) -> Result<(), ConfigError>

Reconfigure the driver

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

Perform a blocking UART write

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

Block until transmission complete

pub fn send_break(&self)

Send break character

Write an entire buffer into this writer.

impl<M: Mode> Write for UartTx<'_, M>

fn write(&mut self, buf: &[u8]) -> Result<usize, Self::Error>

Write a buffer into this writer, returning how many bytes were written.

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

Flush this output stream, blocking until all intermediately buffered contents reach their destination.

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

Write an entire buffer into this writer.

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

fn write(&mut self, char: 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.
