Struct embassy_rp::uart::BufferedUartTx

pub struct BufferedUartTx<'d, T: Instance> { /* private fields */ }

Buffered UART TX handle.

Implementations

impl<'d, T: Instance> BufferedUartTx<'d, T>

pub fn new( _uart: impl Peripheral<P = T> + 'd, irq: impl Binding<T::Interrupt, BufferedInterruptHandler<T>>, tx: impl Peripheral<P = impl TxPin<T>> + 'd, tx_buffer: &'d mut [u8], config: Config ) -> Self

Create a new buffered UART TX.

pub fn new_with_cts( _uart: impl Peripheral<P = T> + 'd, irq: impl Binding<T::Interrupt, BufferedInterruptHandler<T>>, tx: impl Peripheral<P = impl TxPin<T>> + 'd, cts: impl Peripheral<P = impl CtsPin<T>> + 'd, tx_buffer: &'d mut [u8], config: Config ) -> Self

Create a new buffered UART TX with flow control.

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

Write to UART TX buffer blocking execution until done.

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

Flush UART TX blocking execution until done.

pub fn busy(&self) -> bool

Check if UART is busy.

pub async fn send_break(&mut self, bits: u32)

Assert a break condition after waiting for the transmit buffers to empty, for the specified number of bit times. This condition must be asserted for at least two frame times to be effective, bits will adjusted according to frame size, parity, and stop bit settings to ensure this.

This method may block for a long amount of time since it has to wait for the transmit fifo to empty, which may take a while on slow links.

Trait Implementations

impl<'d, T: Instance> Drop for BufferedUartTx<'d, T>

fn drop(&mut self)

impl<'d, T: Instance + 'd> Write for BufferedUartTx<'d, T>

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

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

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

impl<'d, T: Instance> Write for BufferedUartTx<'d, T>

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.

impl<'d, T: Instance + 'd> Write for BufferedUartTx<'d, T>

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.

Write an entire buffer into this writer.

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

Write a formatted string into this writer, returning any error encountered.

impl<'d, T: Instance> Write<u8> for BufferedUartTx<'d, T>

type Error = Error
