1、Four short words sum up what has lifted most successful individuals above the crowd: a little bit more.-author-dateC#的串口通信源程序基于单片机串口通信的上位机和下位机实践 基于单片机串口通信的上位机和下位机首先亮出C#的源程序吧。主要界面：只是作为简单的运用，可以扩展的。源代码：using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using Sys

2、tem.Drawing;using System.Text;using System.Windows.Forms;using System.IO.Ports;using System.Timers;namespace 单片机功能控制 public partial class Form1 : Form public Form1() InitializeComponent(); SerialPort sp = new SerialPort(); private void button1_Click(object sender, EventArgs e) String str1 = comboBox

3、1.Text;/串口号 String str2 = comboBox2.Text;/波特率 String str3 = comboBox3.Text;/校验位 String str4 = comboBox5.Text;/停止位 String str5 = comboBox4.Text;/数据位 Int32 int2 = Convert.ToInt32(str2);/将字符串转为整型 Int32 int5 = Convert.ToInt32(str5);/将字符串转为整型 groupBox3.Enabled = true;/LED控制界面变可选 try if (button1.Text = 打开

4、串口) if (str1 = null) MessageBox.Show(请先选择串口！, Error); return; sp.Close(); sp = new SerialPort(); sp.PortName = comboBox1.Text;/串口编号 sp.BaudRate = int2;/波特率 switch (str4)/停止位 case 1: sp.StopBits = StopBits.One; break; case 1.5: sp.StopBits = StopBits.OnePointFive; break; case 2: sp.StopBits = StopBit
