Struct MmioPort 

pub struct MmioPort { /* private fields */ }

Implementations

impl MmioPort

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 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 receive(&mut self) -> u8

Receives a byte on the serial port.
