[−][src]Module gd32vf103xx_hal::serial
Serial Communication (USART)
This module contains the functions to utilize the USART (Universal synchronous asynchronous receiver transmitter)
Example usage:
// prelude: create handles to the peripherals and registers let p = crate::pac::Peripherals::take().unwrap(); let mut afio = p.AFIO.constrain(&mut rcu); let mut gpioa = p.GPIOA.split(); // USART0 on Pins A9 and A10 let pin_tx = gpioa.pa9; let pin_rx = gpioa.pa10; // Create an interface struct for USART0 with 9600 Baud let serial = Serial::new( p.USART0, (pin_tx, pin_rx), Config::default().baudrate(9_600.bps()), &mut afio, &mut rcu, ); // separate into tx and rx channels let (mut tx, mut rx) = serial.split(); // Write 'R' to the USART block!(tx.write(b'R')).ok(); // Receive a byte from the USART and store it in "received" let received = block!(rx.read()).unwrap();
