Struct PioUartTx 

pub struct PioUartTx<'d, PIO: Instance, const SM: usize> { /* private fields */ }

PIO backed Uart transmitter

Implementations

impl<'d, PIO: Instance, const SM: usize> PioUartTx<'d, PIO, SM>

pub fn new( baud: u32, common: &mut Common<'d, PIO>, sm_tx: StateMachine<'d, PIO, SM>, tx_pin: Peri<'d, impl PioPin>, program: &PioUartTxProgram<'d, PIO>, ) -> Self

Configure a pio state machine to use the loaded tx program.

pub async fn write_u8(&mut self, data: u8)

Write a single u8

pub async fn write(&mut self, buf: &[u8])

Write all bytes in buf.

Returns once all bytes have been pushed into the state machine’s TX FIFO.

pub async fn flush(&mut self)

Wait until all written bytes have been fully transmitted on the wire.

pub fn set_baudrate(&mut self, baud: u32)

Change baud rate on run time

Trait Implementations

impl<PIO: Instance, const SM: usize> ErrorType for PioUartTx<'_, PIO, SM>

type Error = !

Error type of all the IO operations on this type.

impl<PIO: Instance, const SM: usize> Write for PioUartTx<'_, PIO, SM>

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

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

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

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

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

Write an entire buffer into this writer.
