Struct arm_pl011::pl011::Pl011Uart

pub struct Pl011Uart { /* private fields */ }

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

impl Pl011Uart

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

Constrcut a new Pl011 UART instance from the base address.

pub fn init(&mut self)

Initializes the Pl011 UART.

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

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

Output a char c to data register

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

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

pub fn is_receive_interrupt(&self) -> bool

Return true if pl011 has received an interrupt

pub fn ack_interrupts(&mut self)

Clear all interrupts
