pub struct LpUart { /* private fields */ }

LP-UART driver

Implementations

impl LpUart

pub fn read_byte(&mut self) -> Result<u8, Error>

Read a single byte from the UART in a non-blocking manner.

pub fn write_byte(&mut self, byte: u8) -> Result<(), Error>

Write a single byte to the UART in a non-blocking manner.

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

Write one or more byte to the UART, blocking until the write has completed.

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

Flush the UART’s transmit buffer in a non-blocking manner.

Trait Implementations

impl ErrorType for LpUart

type Error = Error

Error type

impl ErrorType for LpUart

type Error = Error

Error type of all the IO operations on this type.

impl Read for LpUart

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

Reads a single word from the serial interface

impl Read for LpUart

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 ReadReady for LpUart

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

Get whether the reader is ready for immediately reading.

impl Write for LpUart

fn write_str(&mut self, s: &str) -> Result

Writes a string slice into this writer, returning whether the write succeeded.

fn write_char(&mut self, c: char) -> Result<(), Error>

Writes a [char] into this writer, returning whether the write succeeded.

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

Glue for usage of the [write!] macro with implementors of this trait.

impl Write for LpUart

fn write(&mut self, word: 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 Write for LpUart

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.
