Module stm32f1xx_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 cp = cortex_m::Peripherals::take().unwrap();
let mut flash = p.FLASH.constrain();
let mut rcc = p.RCC.constrain();
let clocks = rcc.cfgr.freeze(&mut flash.acr);
let mut afio = p.AFIO.constrain(&mut rcc.apb2);
let mut gpioa = p.GPIOA.split(&mut rcc.apb2);

// USART1 on Pins A9 and A10
let pin_tx = gpioa.pa9.into_alternate_push_pull(&mut gpioa.crh);
let pin_rx = gpioa.pa10;
// Create an interface struct for USART1 with 9600 Baud
let serial = Serial::usart1(
   p.USART1,
   (pin_tx, pin_rx),
   &mut afio.mapr,
   Config::default().baudrate(9_600.bps()),
   clocks,
   &mut rcc.apb2,
);

// 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();
