Basic usage of the pl011-uart crate

use pl011_uart::Uart;
use core::fmt::Write;

fn main() {
    // constants required for initializing the UART.
    const PL011_BASE_ADDRESS: *mut u32 = 0x0900_0000 as _;
    const PL011_BAUD_RATE: u32 = 115200;
    const PL011_CLK_IN_HZ: u32 = 50000000;

    // initialize PL011 UART.
    let mut uart = unsafe { Uart::new(PL011_BASE_ADDRESS) };
    uart.init(PL011_CLK_IN_HZ, PL011_BAUD_RATE);

    // write to PL011 UART.
    writeln!(uart, "Hello, World!").unwrap();
