分享一个写得不错的C sharp串口调试工具的源代码!
C sharp源程序如下:
- using System;
- using System.Collections.Generic;
- using System.ComponentModel;
- using System.Data;
- using System.Drawing;
- using System.Linq;
- using System.Text;
- using System.Windows.Forms;
- using System.IO.Ports;
- namespace project4
- {
- public partial class Form1 : Form
- {
- public Form1()
- {
- InitializeComponent();
- System.Windows.Forms.Control.CheckForIllegalCrossThreadCalls = false;
- }
- private void button1_Click(object sender, EventArgs e)
- {
- try
- {
- serialPort1.PortName = comboBox1.Text;//设置串口号
- serialPort1.BaudRate = Convert.ToInt32(comboBox2.Text, 10);//十进制数据转换,设置波特率
- serialPort1.Open();//打开串口
- button1.Enabled = false;//打开串口按钮不可用
- button2.Enabled = true;//关闭串口按钮可用
- }
- catch
- {
- MessageBox.Show("端口错误,请检查串口", "错误");
- }
- }
- private void Form1_Load(object sender, EventArgs e)
- {
- for (int i = 1; i < 20; i++)
- {
- comboBox1.Items.Add("COM" + i.ToString());
- }
- comboBox1.Text = "COM3";//串口号默认值
- comboBox2.Text = "9600";//波特率默认值
- serialPort1.DataReceived += new SerialDataReceivedEventHandler(serialPort1_DataReceived);//添加事件处理程序
- }
- private void serialPort1_DataReceived(object sender, SerialDataReceivedEventArgs e)
- {
- if (!radioButton3.Checked)//如果接收模式为字符模式
- {
- string str = serialPort1.ReadExisting();//字符串方式读
- textBox1.AppendText(str);//添加内容textBox文本框中依次向后显示
- }
- else //如果接收模式为数值接收
- {
- //易出现异常:由于线程退出或应用程序请求,已中止 I/O 操作
- //加入异常处理
- try
- {
- int data;
- data = serialPort1.ReadByte();
- string str = Convert.ToString(data, 16).ToUpper();//转换为大写十六进制字符串
- textBox1.AppendText("0x" + (str.Length == 1 ? "0" + str : str) + " ");//空位补“0”
- }
- catch
- {
- this.Close();//关闭当前窗体
- }
- }
- }

- }
- }
- private void button3_Click(object sender, EventArgs e)

- {
- if (textBox2.Text != "")

- if (!radioButton1.Checked)//如果发送模式是字符模式
- {
- try
- {
- serialPort1.WriteLine(textBox2.Text);//写数据
- }
- catch
- {

- serialPort1.Close();
- button1.Enabled = true;//打开串口按钮可用
- button2.Enabled = false;//关闭串口按钮不可用
- }
- }
- else
- {
- for (int i = 0; i < (textBox2.Text.Length - textBox2.Text.Length % 2) / 2; i++)//取余3运算作用是防止用户输入的字符为奇数个
- {
- Data[0] = Convert.ToByte(textBox2.Text.Substring(i * 2, 2), 16);
- serialPort1.Write(Data, 0, 1);//循环发送(如果输入字符为0A0BB,则只发送0A,0B)
- }
- if (textBox2.Text.Length % 2 != 0)//剩下一位单独处理
- {
- Data[0] = Convert.ToByte(textBox2.Text.Substring(textBox2.Text.Length - 1, 1), 16);//单独发送B(0B)
- serialPort1.Write(Data, 0, 1);//发送
- }
- }
- }
- }
- }
-
- private void textBox2_TextChanged(object sender, EventArgs e)

- else

- }
- private void button4_Click(object sender, EventArgs e)
- {
- textBox1.Text="";//清屏
- }
- private void button5_Click(object sender, EventArgs e)
- {
- this.Close();
- }
- }
- }
