Struct BufferedUartTx

pub struct BufferedUartTx<'d> { /* private fields */ }

Tx-only buffered UART.

Can be obtained from BufferedUart::split, or can be constructed independently, if you do not need the receiving half of the driver.

Implementations

impl<'d> BufferedUartTx<'d>

pub fn new<T: Instance>( uart: Peri<'d, T>, tx: Peri<'d, impl TxPin<T>>, _irq: impl Binding<T::Interrupt, BufferedInterruptHandler<T>>, tx_buffer: &'d mut [u8], config: Config, ) -> Result<Self, ConfigError>

Create a new tx-only buffered UART with no hardware flow control.

Useful if you only want Uart Tx. It saves 1 pin.

pub fn new_with_rts<T: Instance>( uart: Peri<'d, T>, tx: Peri<'d, impl TxPin<T>>, cts: Peri<'d, impl CtsPin<T>>, _irq: impl Binding<T::Interrupt, BufferedInterruptHandler<T>>, tx_buffer: &'d mut [u8], config: Config, ) -> Result<Self, ConfigError>

Create a new tx-only buffered UART with a clear-to-send pin

pub fn set_config(&mut self, config: &Config) -> Result<(), ConfigError>

Reconfigure the driver

pub fn set_baudrate(&self, baudrate: u32) -> Result<(), ConfigError>

Set baudrate

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

Write to UART TX buffer, blocking execution until done.

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

Flush UART TX buffer, blocking execution until done.

pub fn busy(&self) -> bool

Check if UART is busy.

pub fn send_break(&mut self)

Send break character

Trait Implementations

impl Drop for BufferedUartTx<'_>

fn drop(&mut self)

Executes the destructor for this type.

impl ErrorType for BufferedUartTx<'_>

type Error = Error

Error type of all the IO operations on this type.

impl ErrorType for BufferedUartTx<'_>

type Error = Error

Error type

impl SetConfig for BufferedUartTx<'_>

type Config = Config

The configuration type used by this driver.

type ConfigError = ConfigError

The error type that can occur if set_config fails.

fn set_config(&mut self, config: &Self::Config) -> Result<(), Self::ConfigError>

Set the configuration of the driver.

impl Write for BufferedUartTx<'_>

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>

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.

impl Write for BufferedUartTx<'_>

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 Write for BufferedUartTx<'_>

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.
