Macro arduino_hal::default_serial

macro_rules! default_serial {
    ($p:expr, $pins:expr, $baud:expr) => { ... };
}

Convenience macro to instantiate the Usart driver for this board.

Example

let dp = arduino_hal::Peripherals::take().unwrap();
let pins = arduino_hal::pins!(dp);
let serial = arduino_hal::default_serial!(dp, pins, 57600);

This is equivalent to manually configuring the driver:

let dp = arduino_hal::Peripherals::take().unwrap();
let pins = arduino_hal::pins!(dp);
let serial = arduino_hal::Usart::new(
    dp.USART1,
    pins.d0,
    pins.d1.into_output(),
    // See src/usart.rs for why some boards use the BaudrateArduinoExt trait
    // instead of BaudrateExt.
    arduino_hal::hal::usart::BaudrateArduinoExt::into_baudrate(57600),
);
