Struct Uarte

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

UARTE driver.

Implementations

impl<'d, T: Instance> Uarte<'d, T>

pub fn new( uarte: impl Peripheral<P = T> + 'd, _irq: impl Binding<T::Interrupt, InterruptHandler<T>> + 'd, rxd: impl Peripheral<P = impl GpioPin> + 'd, txd: impl Peripheral<P = impl GpioPin> + 'd, config: Config, ) -> Self

Create a new UARTE without hardware flow control

pub fn new_with_rtscts( uarte: impl Peripheral<P = T> + 'd, _irq: impl Binding<T::Interrupt, InterruptHandler<T>> + 'd, rxd: impl Peripheral<P = impl GpioPin> + 'd, txd: impl Peripheral<P = impl GpioPin> + 'd, cts: impl Peripheral<P = impl GpioPin> + 'd, rts: impl Peripheral<P = impl GpioPin> + 'd, config: Config, ) -> Self

Create a new UARTE with hardware flow control (RTS/CTS)

pub fn split(self) -> (UarteTx<'d, T>, UarteRx<'d, T>)

Split the Uarte into the transmitter and receiver parts.

This is useful to concurrently transmit and receive from independent tasks.

pub fn split_by_ref(&mut self) -> (&mut UarteTx<'d, T>, &mut UarteRx<'d, T>)

Split the UART in reader and writer parts, by reference.

The returned halves borrow from self, so you can drop them and go back to using the “un-split” self. This allows temporarily splitting the UART.

pub fn split_with_idle<U: TimerInstance>( self, timer: impl Peripheral<P = U> + 'd, ppi_ch1: impl Peripheral<P = impl ConfigurableChannel + 'd> + 'd, ppi_ch2: impl Peripheral<P = impl ConfigurableChannel + 'd> + 'd, ) -> (UarteTx<'d, T>, UarteRxWithIdle<'d, T, U>)

Split the Uarte into the transmitter and receiver with idle support parts.

This is useful to concurrently transmit and receive from independent tasks.

pub fn event_endtx(&self) -> Event<'_>

Return the endtx event for use with PPI

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

Read bytes until the buffer is filled.

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

Write all bytes in the buffer.

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

Same as write but will fail instead of copying data into RAM. Consult the module level documentation to learn more.

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

Read bytes until the buffer is filled.

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

Write all bytes in the buffer.

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

Same as blocking_write but will fail instead of copying data into RAM. Consult the module level documentation to learn more.

Trait Implementations

impl<'d, U: Instance> ErrorType for Uarte<'d, U>

type Error = Error

Error type of all the IO operations on this type.

impl<'d, U: Instance> Write for Uarte<'d, U>

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<'d, T: Instance> Write<u8> for Uarte<'d, T>

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
