Struct Usart

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

Type parameters

’d: the lifetime marker ensuring correct borrow checking for peripherals used at compile time T: the peripheral instance type allowing usage of peripheral specific registers M: the operating mode of USART peripheral

Implementations

impl<'d> Usart<'d, Blocking>

pub fn new_blocking<T: Instance>( usart: Peri<'d, T>, tx: Peri<'d, impl TxPin<T>>, rx: Peri<'d, impl RxPin<T>>, config: Config, ) -> Self

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

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 USART TX blocking execution until done.

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

Read from USART RX blocking execution until done.

pub fn tx_busy(&self) -> bool

Check if UART is busy transmitting.

pub fn split(self) -> (UsartTx<'d, M>, UsartRx<'d, M>)

Split the Usart into a transmitter and receiver, which is particularly useful when having two tasks correlating to transmitting and receiving.

pub fn split_ref(&mut self) -> (&mut UsartTx<'d, M>, &mut UsartRx<'d, M>)

Split the Usart into a transmitter and receiver by mutable reference, which is particularly useful when having two tasks correlating to transmitting and receiving.

Trait Implementations

impl<'d> ErrorType for Usart<'d, Blocking>

type Error = Error

Error type of all the IO operations on this type.

impl<'d> Read for Usart<'d, Blocking>

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

Read some bytes from this source into the specified buffer, returning how many bytes were read.

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

Read the exact number of bytes required to fill buf.

impl<'d> Write for Usart<'d, Blocking>

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>>

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

impl<'d, M: Mode> Write<u8> for Usart<'d, M>

type Error = Error

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

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

Block until the serial interface has sent all buffered words
