Module imxrt_hal::uart

Low Power Universal Asynchronous Receiver/Transmit (LPUART)

The UART module provides a serial peripheral that implements the embedded_hal::serial traits. The peripheral is sufficient for implementing basic serial communications.

UARTs may also be used in bi-directional DMA transfers.

Example

use imxrt_hal;
use embedded_hal::serial::{Read, Write};

let mut peripherals = imxrt_hal::Peripherals::take().unwrap();

let uarts = peripherals.uart.clock(
    &mut peripherals.ccm.handle,
    imxrt_hal::ccm::uart::ClockSelect::OSC,
    imxrt_hal::ccm::uart::PrescalarSelect::DIVIDE_1,
);

let mut uart = uarts
    .uart2
    .init(
        peripherals.iomuxc.ad_b1.p02,
        peripherals.iomuxc.ad_b1.p03,
        115_200,
    )
    .unwrap();

uart.set_tx_fifo(core::num::NonZeroU8::new(3));
uart.set_rx_fifo(true);
uart.set_parity(Some(imxrt_hal::uart::Parity::Even));
uart.set_rx_inversion(true);
uart.set_tx_inversion(false);

uart.write(0xDE).unwrap();
let byte = uart.read().unwrap();

// Split the peripheral into transfer and receive halves
let (tx, rx) = uart.split();
