Continuous Write using USART

To write string continuously using USART, our code will perform the following opertions.

• Disable watchdog
• Create a new Serial struct to access all USART's
• initialize USART0 and makes it ready to transmit and recieve.
• Loop to send a string using the USART multiple times.This sends string from arduino through TxD0 pin.
• Disable USART0.

pub fn main() {

let watchdog = unsafe { WatchDog::new() };

watchdog.disable();

let mut serial = unsafe { Serial::new() };

unsafe { serial.usart[0].begin() };

let mut i: u8 = 100;

while i != 0 {

serial.usart[0].write_string("Hello World!");

rustduino::delay::delay_ms(1000);

i = i - 1;

}

unsafe { serial.usart[0].end() };

}
