Expand description

The Pl011 Uart

The Pl011 Uart provides a programing interface for:

  1. Construct a new Pl011 UART instance
  2. Initialize the Pl011 UART
  3. Read a char from the UART
  4. Write a char to the UART
  5. Handle a UART IRQ

Implementations§

source§

impl Pl011Uart

source

pub const fn new(base: *mut u8) -> Self

Constrcut a new Pl011 UART instance from the base address.

source

pub fn init(&mut self)

Initializes the Pl011 UART.

It clears all irqs, sets fifo trigger level, enables rx interrupt, enables receives

source

pub fn putchar(&mut self, c: u8)

Output a char c to data register

source

pub fn getchar(&mut self) -> Option<u8>

Return a byte if pl011 has received, or it will return None.

source

pub fn is_receive_interrupt(&self) -> bool

Return true if pl011 has received an interrupt

source

pub fn ack_interrupts(&mut self)

Clear all interrupts
