Module atmega_hal::usart

USART

Example

Complete example source code can be found in the repository: atmega2560-usart.rs

Note: ufmt is used instead of core::fmt because core::fmt code quickly grows too large for AVR platforms.

let dp = atmega_hal::Peripherals::take().unwrap();
let pins = atmega_hal::pins!(dp);

let mut serial = Usart::new(
    dp.USART0,
    pins.pe0,
    pins.pe1.into_output(),
    Baudrate::<crate::CoreClock>::new(57600),
);

ufmt::uwriteln!(&mut serial, "Hello from ATmega!").unwrap();

loop {
    // Read a byte from the serial connection
    let b = nb::block!(serial.read()).unwrap();
    // Answer
    ufmt::uwriteln!(&mut serial, "Got {}!", b).unwrap();
}

Structs

• Baudrate
  Representation of a USART baudrate

Enums

• Event
  Events/Interrupts for USART peripherals

Traits

• BaudrateArduinoExt
  Same as BaudrateExt but accounts for an errata of certain Arduino boards:
• BaudrateExt
  Provide a into_baudrate() method for integers.
• UsartOps
  Internal trait for low-level USART peripherals.

Type Aliases

• Usart
• Usart0
• UsartReader
• UsartWriter
