win10系统rust串口通信实现

一、用cargo创建新工程

命令：cargo new comport

use std::env;
use std::{thread, time};
use serialport::{DataBits, StopBits, Parity, FlowControl};
use std::io::{self, Read, Write};
use std::time::Duration;fn main() -> io::Result<()> {let mut args: Vec<String> = env::args().collect();if args.len() < 1+3 {println!("{} ComPort Baudrate Command [DelayMS]",args[0]);std::process::exit(-1);}let mut duration: u64 = 100;//secondsif args.len() > 1+3 {duration = args[args.len()-1].parse::<u64>().unwrap();}let mut port = serialport::new(&args[1], args[1+1].parse::<u32>().unwrap()).data_bits(DataBits::Eight).stop_bits(StopBits::One).parity(Parity::None).flow_control(FlowControl::None).timeout(Duration::from_secs(1)).open()?;let offset = 1+1+1;args[offset]=args[offset].replace("\\r", "\r");args[offset]=args[offset].replace("\\n", "\n"); let data = &args[offset];port.write_all(data.as_bytes())?;thread::sleep(time::Duration::from_millis(duration));let mut buffer: Vec<u8> = vec![0; 80000000];let bytes_read = port.read(buffer.as_mut_slice())?;let received_data = String::from_utf8_lossy(&buffer[..bytes_read]);println!("Received: {}", received_data);Ok(())}
