Struct MmioSerialPort

pub struct MmioSerialPort { /* private fields */ }

A memory-mapped UART.

Implementations

impl MmioSerialPort

pub const unsafe fn new(base: usize) -> Self

Creates a new UART interface on the given memory mapped address.

This function is unsafe because the caller must ensure that the given base address really points to a serial port device.

pub const unsafe fn new_with_stride(base: usize, stride: usize) -> Self

Creates a new UART interface on the given memory mapped address with a given register stride.

This function is unsafe because the caller must ensure that the given base address really points to a serial port device.

pub fn init(&mut self)

Initializes the memory-mapped UART.

The default configuration of 38400/8-N-1 is used.

pub fn send(&mut self, data: u8)

Sends a byte on the serial port.

pub fn send_raw(&mut self, data: u8)

Sends a raw byte on the serial port, intended for binary data.

pub fn try_send_raw(&mut self, data: u8) -> Result<(), WouldBlockError>

Tries to send a raw byte on the serial port, intended for binary data.

pub fn receive(&mut self) -> u8

Receives a byte on the serial port.

pub fn try_receive(&mut self) -> Result<u8, WouldBlockError>

Tries to receive a byte on the serial port.

Trait Implementations

impl Debug for MmioSerialPort

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Write for MmioSerialPort

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.
