Struct Uart

pub struct Uart<A: UartAddress, M: Mode> { /* private fields */ }

Implementations

impl<A: UartAddress, M: Mode> Uart<A, M>

pub fn read_interrupt_status(&self) -> InterruptStatus

Read from the interrupt status register.

pub fn write_fifo_control(&mut self, fifo_control: FifoControl)

Write to the FIFO control register.

pub fn read_line_control(&self) -> LineControl

Read from the line control register.

pub fn write_line_control(&mut self, value: LineControl)

Write to the line control register.

pub fn write_modem_control(&mut self, value: ModemControl)

Write to the modem control register.

pub fn read_line_status(&mut self) -> LineStatus

Read from the line status register.

pub fn read_modem_status(&self) -> ModemStatus

Read from the modem status register.

impl<A: UartAddress> Uart<A, DLAB>

pub unsafe fn new(base_address: A) -> Self

Creates a new Uart pointing to base_address.

Safety

• Provided address must be valid as the base address of a UART device.
• Provided address must not be otherwise mutably aliased.
• Device must have bit 7 of the line control register (DLAB enable) set to 1.

pub fn get_baud(&self) -> Baud

Read from the baud rate from the divisor latch registers.

pub fn set_baud(&mut self, baud: Baud)

Set the baud rate using the divisor latch registers.

pub fn into_data_mode(self) -> Uart<A, Data>

Disables access to the divisor latch registers.

impl<A: UartAddress> Uart<A, Data>

pub unsafe fn new(base_address: A) -> Self

Creates a new Uart pointing to base_address.

Safety

• UART must have bit 7 of the line control register (DLAB enable) set to 0.

pub fn new_reset(base_address: A) -> Self

Creates a new Uart pointing to base_address, and resets all the control and holding registers.

pub fn read_byte(&mut self) -> u8

Reads a byte from the receiver holding register.

pub fn write_byte(&mut self, byte: u8)

Writes a byte to the transmitter holding register

pub fn read_interrupt_enable(&self) -> InterruptEnable

Reads from the interrupt enable register.

pub fn write_interrupt_enable(&mut self, value: InterruptEnable)

Writes to the interrupt enable register.

pub fn into_dlab_mode(self) -> Uart<A, DLAB>

Enables access to the divisor latch registers.
