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 = env::args().collect();

if args.len() < 1+3 {

println!("{} ComPort Baudrate Command [DelayMS]",args[0]);

std::process::exit(-1);

}

let mut duration: u64 = 100;//seconds

if args.len() > 1+3 {

duration = args[args.len()-1].parse::().unwrap();

}

let mut port = serialport::new(&args[1], args[1+1].parse::().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 = 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(())

}

二、进入到新建工程文件夹并编译

命令：cd ./comport && cargo build

三、运行上面编译的工程

命令输入格式：cargo run COM6 921600 "AT\n"
