Implementations

impl Uart

const INIT_CALLED: u8

const USABLE: u8

pub fn new(base_addr: u16) -> Self

Constructor; creates a new uninitialized Uart device with the given base_addr

pub fn com1() -> Self

Wrapper around Self::new; creates a Uart device with a base_addr of 0x3F8

pub fn com2() -> Self

Wrapper around Self::new; creates a Uart device with a base_addr of 0x2F8

pub fn com3() -> Self

Wrapper around Self::new; creates a Uart device with a base_addr of 0x3E8

pub fn com4() -> Self

Wrapper around Self::new; creates a Uart device with a base_addr of 0x2E8

fn reg(&self, offset: u16) -> Port<u8>

Returns the I/O port at offset from this UART device’s base_addr

fn is_usable(&self) -> bool

Checks if the given device is usable (fully initialized)

Trait Implementations

impl UartOps for Uart

fn init(&mut self) -> Result<(), UartError>

Initialize the UART device

fn read_byte(&mut self) -> Result<u8, UartError>

Read one byte from the UART device

fn write_byte(&mut self, byte: u8) -> Result<(), UartError>

Write one byte to the UART device

fn write_string(&mut self, string: &str) -> Result<(), UartError>

Write a string to the serial device Default implementation calls Self::write_byte for each byte in the string
