Struct Uart 

pub struct Uart<'a> { /* private fields */ }

PL011 UART implementation

Implementations

impl<'a> Uart<'a>

pub fn new(regs: UniqueMmioPointer<'a, PL011Registers>) -> Self

Creates new UART instance.

pub fn enable( &mut self, config: LineConfig, baud_rate: u32, sysclk: u32, ) -> Result<(), Error>

Configure and enable UART

pub fn disable(&mut self)

Disable UART

pub fn is_rx_fifo_empty(&self) -> bool

Check if receive FIFO is empty

pub fn is_rx_fifo_full(&self) -> bool

Check if receive FIFO is full

pub fn is_tx_fifo_empty(&self) -> bool

Check if transmit FIFO is empty

pub fn is_tx_fifo_full(&self) -> bool

Check if transmit FIFO is full

pub fn is_busy(&self) -> bool

Check if UART is busy

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

Non-blocking read of a single byte from the UART.

Returns Ok(None) if no data is available to read.

pub fn write_word(&mut self, word: u8)

Non-blocking write of a single byte to the UART

pub fn read_identification(&self) -> Identification

Read UART peripheral identification structure

pub fn set_interrupt_fifo_levels( &mut self, rx_level: FifoLevel, tx_level: FifoLevel, )

Sets trigger levels for RX and TX interrupts. The interrupts are generated when the fill level progresses through the trigger level.

pub fn raw_interrupt_status(&self) -> Interrupts

Reads the raw interrupt status register.

pub fn masked_interrupt_status(&self) -> Interrupts

Reads the masked interrupt status register.

pub fn interrupt_masks(&self) -> Interrupts

Returns the current set of interrupt masks.

pub fn set_interrupt_masks(&mut self, masks: Interrupts)

Sets the interrupt masks.

pub fn clear_interrupts(&mut self, interrupts: Interrupts)

Clears the given set of interrupts.

Trait Implementations

impl ErrorType for Uart<'_>

type Error = Error

Error type

impl ErrorType for Uart<'_>

type Error = Error

Error type of all the IO operations on this type.

impl Read for Uart<'_>

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

Reads a single word from the serial interface

impl Read for Uart<'_>

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>>

impl Write for Uart<'_>

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 Uart<'_>

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>
