1、using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.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
2、 sp = new SerialPort(); private void button1_Click(object sender, EventArgs e) String str1 = comboBox1.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
3、int5 = Convert.ToInt32(str5); groupBox3.Enabled = true;/LED控制界面变可选 try if (button1.Text = 打开串口) 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; switch (str4)/停止位 case 1: sp.StopBits = StopBits.One; br
4、eak;1.5 sp.StopBits = StopBits.OnePointFive;2 sp.StopBits = StopBits.Two; default:Error:参数不正确 switch (str3)NONE sp.Parity = Parity.None;ODD sp.Parity = Parity.Odd;EVEN sp.Parity = Parity.Even; sp.DataBits = int5;/设置串口属性 sp.Open();/打开串口 button1.Text = 关闭串口; textBox1.Text = Convert.ToString(sp.PortNam
5、e) + 已开启! else groupBox3.Enabled = false;/LED控制界面变灰色 已关闭! catch (Exception er)Error: + er.Message, private void Form1_Load(object sender, EventArgs e) /初始化 textBox1.Text = 欢迎使用简易的串口助手! groupBox6.Enabled = false; groupBox7.Enabled = false; groupBox8.Enabled = false; button3.Enabled = false; button6.E
6、nabled = false; timer1.Start(); foreach (string com in System.IO.Ports.SerialPort.GetPortNames() /自动获取串行口名称 boBox1.Items.Add(com); /默认设置 comboBox1.SelectedIndex = 0;/选择第一个com口 comboBox2.SelectedIndex = 4;/波特率4800 comboBox3.SelectedIndex = 0;/校验位NONE comboBox4.SelectedIndex = 0;/停止位为1 comboBox5.Selec
7、tedIndex = 0;/数据位为8 catch找不到通讯端口!串口调试助手 private void timer1_Tick(object sender, EventArgs e) label6.Text = DateTime.Now.ToString(); private void button2_Click(object sender, EventArgs e) try if (button2.Text = 开启 groupBox6.Enabled = true; radioButton1.Checked = false; radioButton2.Checked = false; r
8、adioButton3.Checked = false; radioButton4.Checked = false; checkBox1.Checked = false; checkBox2.Checked = false; checkBox3.Checked = false; checkBox4.Checked = false; checkBox5.Checked = false; checkBox6.Checked = false; checkBox7.Checked = false; checkBox8.Checked = false; button3.Enabled = true; t
9、extBox2.Text = String.Empty; button2.Text = 关闭 private void button3_Click(object sender, EventArgs e) label7.Text = 已发送 if (textBox2.Text = 发送失败,请选择发送的数据! sp.WriteLine(textBox2.Text);/往串口写数据 private void checkBox1_CheckedChanged(object sender, EventArgs e) if (checkBox1.Checked) checkBox1.Checked = true;准备发送 textBox2.Text = private void checkBox2_CheckedChanged(object sender, EventArgs e) if (checkBox2.Checked) checkBox2.Checked = true;
