1、串口調試助手預源代碼using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Windows.Forms;using System.IO;using System.IO.Ports;using System.Threading;using DevExpress.XtraEdi

2、tors;using System.Text.RegularExpressions;namespace WindowsFormsApplication3 public partial class Form1 : XtraForm SerialPort sp1 = new SerialPort(); int Flag = 0; int StateChanged = 0; int StateChanged_Ascii = 1; int StateChanged_16 = 0; string Temp = null; string Temp_memoSend = null; private void

3、 memoSend_EditValueChanged(object sender, EventArgs e) public Form1() InitializeComponent(); sp1.DataReceived += sp1_DataReceived; private void Form1_Load(object sender, EventArgs e) this.MaximizeBox = false; /檢查是否有串口 string str = SerialPort.GetPortNames(); if (str = null) MessageBox.Show(本機沒有串口！, e

4、rror); return; /添加串口項目 foreach (string port in System.IO.Ports.SerialPort.GetPortNames() cbSerial.Properties.Items.Add(port); /串口設置默認選擇項 cbSerial.SelectedIndex = 0; Control.CheckForIllegalCrossThreadCalls = false; sp1.DataReceived += new SerialDataReceivedEventHandler(sp1_DataReceived); /訂閱委托 privat

5、e void comboBoxEdit1_SelectedIndexChanged(object sender, EventArgs e) private void OpenSerial_Click(object sender, EventArgs e) sp1.Close(); /SerialPort sp1 = new SerialPort(); if (!sp1.IsOpen)/串口是關閉的，設置參數，打開串口 try /獲取串口號 string serialName = cbSerial.SelectedItem.ToString(); sp1.PortName = serialNam

6、e; /設置各參數 string strBaudRate = cbBaudRate.Text; string strDateBits = cbDataBits.Text; string strStopBits = cbStop.Text; sp1.BaudRate = Convert.ToInt32(strBaudRate);/波特率 sp1.DataBits = Convert.ToInt32(strDateBits);/數據位 switch (cbStop.Text) /停止位 case 1: sp1.StopBits = StopBits.One; break; case 1.5: sp

7、1.StopBits = StopBits.One; break; case 2: sp1.StopBits = StopBits.Two; break; default: MessageBox.Show(Error:參數不正確！, Error); break; switch (cbParity.Text) /校驗位 case 無: sp1.Parity = Parity.None; break; case 奇校驗: sp1.Parity = Parity.Odd; break; case 偶校驗: sp1.Parity = Parity.Even; break; default: Messa

8、geBox.Show(Error:參數不正確！, Error); break; if (sp1.IsOpen = true) sp1.Close(); sp1.Open(); /btnOpen.Enabled = false; labSerial.Text = 串口號： + sp1.PortName; labState.Text = 狀 態：打開; catch (System.Exception ex) MessageBox.Show(Error: + ex.Message, Error); return; /private void CloseSerial_Click(object send

9、er, EventArgs e) / / if (sp1.IsOpen) / / sp1.Close(); / labSerial.Text = 串口號： + sp1.PortName; / labState.Text = 狀 態：關閉; / / private void Send_Click(object sender, EventArgs e) string StrSend = memoSend.Text; if (!sp1.IsOpen) MessageBox.Show(請先打開串口！, Error); return; else if (rbtnSendStr.Checked) /字符串

10、發送 if (ckTimeSend.Checked & !(string.IsNullOrEmpty(textTime.Text)/判斷是否定時發送數據 string Time = textTime.Text; tmSend.Interval = int.Parse(Time) * 1000;/時間單位是秒，化成毫秒單位 tmSend.Start(); /開啟定時器 else sp1.Write(StrSend); /寫入數據 else /十六進制發送 if (ckTimeSend.Checked & !(string.IsNullOrEmpty(textTime.Text) string T

11、ime = textTime.Text; tmSend.Interval = int.Parse(Time) * 1000; tmSend.Start(); else string StrSend_1 = StrSend.Trim(); /去掉前后的空格 /string StrSend_2 = StrSend_1.Replace( , ); /string StrSend_3 = string.Join( , Regex.Matches(StrSend_2, .|.).Cast().ToList(); string StrArray = StrSend_1.Split( ); /用空格符隔開字

12、符串數組 var Str_Send = new List(); / int byteBufferLength = StrArray.Length; /數組StrArray的長度 for (int i = 0; i StrArray.Length; i+) if (StrArrayi.Trim() = ) /byteBufferLength-; continue; else if (StrArrayi.Length 3) Str_Send.Add(StrArrayi); else Str_Send.AddRange(Devide(StrArrayi); int byteBufferLength

13、= Str_Send.Count; byte byteBuffer = new bytebyteBufferLength; int ii = 0; for (int i = 0; i Str_Send.Count; i+) /Byte bytesOfStr = Encoding.Default.GetBytes(StrArrayi); int decNum = 0; /if (StrArrayi = ) / / continue; / /else / /decNum = Convert.ToInt32(Str_Sendi, 16); /把字符串轉成16進制數 /byteBufferii = C

14、onvert.ToByte(decNum); / try decNum = Convert.ToInt32(Str_Sendi, 16); /把字符串轉成16進制數 byteBufferii = Convert.ToByte(decNum); catch (System.Exception ex) MessageBox.Show(輸入錯誤！, 提示); return; ii+; sp1.Write(byteBuffer, 0, byteBuffer.Length);/從第0個開始寫入byteBuffer，長度bytebuffer的長度。 private List Devide(string s

15、tr) var ret = Regex.Matches(str, .|.).Cast().ToList().ConvertAll(s = s.Value.ToString(); return ret; private void tmSend_Tick(object sender, EventArgs e) string StrSend = memoSend.Text; if (rbtnSendStr.Checked) sp1.Write(StrSend); else string StrSend_1 = StrSend.Trim(); /去掉前后的空格 string StrArray = St

16、rSend_1.Split( ); /用空格符隔開字符串數組 var Str_Send = new List(); for (int i = 0; i StrArray.Length; i+) if (StrArrayi.Trim() = ) continue; else if (StrArrayi.Length 3) Str_Send.Add(StrArrayi); else Str_Send.AddRange(Devide(StrArrayi); int byteBufferLength = Str_Send.Count; byte byteBuffer = new bytebyteBuf

17、ferLength; int ii = 0; for (int i = 0; i Str_Send.Count; i+) int decNum = 0; try decNum = Convert.ToInt32(Str_Sendi, 16); /把字符串轉成16進制數 byteBufferii = Convert.ToByte(decNum); catch (System.Exception ex) MessageBox.Show(輸入錯誤！, 提示); return; ii+; sp1.Write(byteBuffer, 0, byteBuffer.Length);/從第0個開始寫入byte

18、Buffer，長度bytebuffer的長度。 void sp1_DataReceived(object sender, SerialDataReceivedEventArgs e) byte byteRead = new bytesp1.BytesToRead; if (rbtnRceStr.Checked) memoRcv.Text += sp1.ReadExisting(); memoRcv.SelectionStart = memoRcv.Text.Length; memoRcv.ScrollToCaret(); else if (rbtnRce16.Checked) Byte rec

19、eivedData = new Bytesp1.BytesToRead; /創建接收字節數組 sp1.Read(receivedData, 0, receivedData.Length); string strRcv = null; for (int i = 0; i receivedData.Length; i+) strRcv += receivedDatai.ToString(X2); memoRcv.Text += strRcv; memoRcv.SelectionStart = memoRcv.Text.Length; memoRcv.ScrollToCaret(); private

20、 void Stop_Click(object sender, EventArgs e) /退出接收數據 tmSend.Stop(); private void Clear_Click(object sender, EventArgs e) /清空接收數據 memoRcv.Text = ; private void Time_Press(object sender, KeyPressEventArgs e) if (!Char.IsLetterOrDigit(e.KeyChar) e.Handled = true; else e.Handled = false; private void Te

21、xtTime_KeyPress(object sender, KeyPressEventArgs e) /限制定時發送時間只能輸入數字 if (!(Char.IsNumber(e.KeyChar) & e.KeyChar != (char)8) MessageBox.Show(請輸入數字, 提示); e.Handled = true; else e.Handled = false; private void memoSend_KeyPress(object sender, KeyPressEventArgs e) private void btnClose_Click(object sende

22、r, EventArgs e) /關閉串口 if (sp1.IsOpen) sp1.Close(); labSerial.Text = 串口號： + sp1.PortName; labState.Text = 狀 態：關閉; private void Send16_KeyPress(object sender, KeyPressEventArgs e) /string Send16 = memoRcv.Text; /byte buff = new byteSend16.Length / 2; /int index = 0; /for (int i = 0; i Send16.Length; i

23、 += 2) / / buffindex = Convert.ToByte(Send16.Substring(i, 2), 16); / +index; / /string result = Encoding.Default.GetString(buff); / MessageBox.Show(result); /memoRcv.Text = result; private void SendStr_KeyPress(object sender, KeyPressEventArgs e) /string SendStr = memoRcv.Text; /byte ba = System.Tex

24、t.ASCIIEncoding.Default.GetBytes(SendStr); /StringBuilder sb = new StringBuilder(); /foreach (byte b in ba) / / sb.Append(b.ToString(x); / / MessageBox.Show(sb.ToString(); /memoRcv.Text = sb.ToString(); private void rbtnSend16_CheckedChanged(object sender, EventArgs e) StateChanged_16 = 1; StateChan

25、ged_Ascii = 0; string StrSend = memoSend.Text; if (Temp_memoSend=StrSend.Trim()& Flag = 1) memoSend.Text = Temp; Flag = 0; else memoSend.Text = ; foreach (char S in StrSend) memoSend.Text += (byte)S).ToString(X2); private void rbtnSendStr_CheckedChanged(object sender, EventArgs e) if (StateChanged_16 = 1) Flag = 1; StateChanged_16 = 0; StateChanged_Ascii = 1; string StrSend = memoSend.Text; Temp = memoSend.Te
