Struct embassy_rp::uart::UartTx

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

UART TX driver.

Implementations

impl<'d, T: Instance, M: Mode> UartTx<'d, T, M>

pub fn new( _uart: impl Peripheral<P = T> + 'd, tx: impl Peripheral<P = impl TxPin<T>> + 'd, tx_dma: impl Peripheral<P = impl Channel> + 'd, config: Config ) -> Self

Create a new DMA-enabled UART which can only send data

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

Transmit the provided 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 transmitting.

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.

impl<'d, T: Instance> UartTx<'d, T, Blocking>

pub fn into_buffered( self, irq: impl Binding<T::Interrupt, BufferedInterruptHandler<T>>, tx_buffer: &'d mut [u8] ) -> BufferedUartTx<'d, T>

Convert this uart TX instance into a buffered uart using the provided irq and transmit buffer.

impl<'d, T: Instance> UartTx<'d, T, Async>

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

Write to UART TX from the provided buffer using DMA.
