Implementations

Create a buffered UART instance.

pub fn new_with_rtscts( _uart: impl Peripheral<P = T> + 'd, irq: impl Binding<T::Interrupt, BufferedInterruptHandler<T>>, tx: impl Peripheral<P = impl TxPin<T>> + 'd, rx: impl Peripheral<P = impl RxPin<T>> + 'd, rts: impl Peripheral<P = impl RtsPin<T>> + 'd, cts: impl Peripheral<P = impl CtsPin<T>> + 'd, tx_buffer: &'d mut [u8], rx_buffer: &'d mut [u8], config: Config, ) -> Self

Create a buffered UART instance with flow control.

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 blocking execution until done.

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

Read from UART RX buffer blocking execution until done.

pub fn busy(&self) -> bool

Check if UART is busy transmitting.

pub async fn send_break(&mut self, bits: u32)

Wait until TX is empty and send break condition.

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

sets baudrate on runtime

pub fn split(self) -> (BufferedUartTx<'d, T>, BufferedUartRx<'d, T>)

Split into separate RX and TX handles.

pub fn split_ref( &mut self, ) -> (&mut BufferedUartTx<'d, T>, &mut BufferedUartRx<'d, T>)

Split the Uart 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, T: Instance + 'd> BufRead for BufferedUart<'d, T>

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

Return the contents of the internal buffer, filling it with more data from the inner reader if it is empty.

fn consume(&mut self, amt: usize)

Tell this buffer that amt bytes have been consumed from the buffer, so they should no longer be returned in calls to fill_buf.

impl<'d, T: Instance> ErrorType for BufferedUart<'d, T>

type Error = Error

Error type of all the IO operations on this type.

impl<'d, T: Instance> ErrorType for BufferedUart<'d, T>

type Error = Error

Error type

async 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.

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