第三方控件TMS、SPComm的下载与安装

盒子上可搜索关键字进行下载,TMS是.dpk文件,SPComm.pas文件;

安装方法自行百度,不做赘述。

 

通过TMS控件进行界面布局

Delphi通过SPComm连接串口、发送和接收指令

连接串口

拖一个TComm控件到主窗体上,选中控件,单击F11,完成如下配置。

这里主要是将一些布尔类型的属性设置成False,其他属性在前台连接按钮事件下动态设置。

连接代码如下,这里需要特别主意一下:

当串口参数超过COM9(即COM10、COM11、COM12...)的时候,SPComm单元中有此BUG,ComName这里不可以直接赋值,需要做如下处理。

CommName := //./‘ + cbbCOM.Text;  

 1 procedure TMainFrm.advBtnConnectClick(Sender: TObject);
 2 var
 3   serialPortNO: string;
 4 begin
 5   try
 6     with comMain do
 7     begin
 8       StopComm;
 9       serialPortNO := Copy(cbbCOM.Text, 4, Length(cbbCOM.Text) - 3);
10       BaudRate := StrToInt(cbbBaudRate.Text);
11 //      ByteSize := TByteSize(cbbByteSize.ItemIndex);
12 //      StopBits := TStopBits(cbbStopBit.ItemIndex);
13 //      Parity := TParity(cbbCheckBit.ItemIndex);
14       if StrToInt(serialPortNO) > 9 then
15       begin
16         CommName := //./‘ + cbbCOM.Text;
17       end
18       else
19       begin
20         CommName := cbbCOM.Text;
21       end;
22       comMain.StartComm;
23       connectStatus.Caption := Connected;
24       connectStatus.FillColor := clLime;
25       advBtnConnect.Enabled := False;
26       gbSendMsg.Enabled := True;
27     end;
28   except
29     connectStatus.Caption := Not Connected;
30     connectStatus.FillColor := clRed;
31     gbSendMsg.Enabled := False;
32   end;
33 
34 end;

 

发送指令

WriteCommData(); 

 1 procedure TMainFrm.advBtnConfirmClick(Sender: TObject);
 2 begin
 3   if mmSendMsg.Lines.Count <= 0 then
 4   begin
 5     Application.MessageBox(‘There is no key word, please check the MsgSendList,thanks.‘, ‘Error Information‘, MB_OK + MB_ICONSTOP);
 6     mmSendMsg.SetFocus;
 7     Exit;
 8   end;
 9   if cbByte.Checked then
10   begin
11     SendHex(mmSendMsg.Text);
12   end
13   else
14   begin
15     comMain.WriteCommData(PChar(mmSendMsg.Text), Length(mmSendMsg.Text));
16   end;
17   if (cbAutoSend.Checked) and (edtTime.Text <> ‘‘) and (cbByte.Checked) then
18   begin
19     timerMain.Interval := StrToInt(edtTime.Text);
20     timerMain.Enabled := True;
21   end;
22 end;

SendHex函数 

 1 procedure TMainFrm.SendHex(S: string);
 2 var
 3   s2: string;
 4   buf1: array[0..50000] of char;
 5   i: integer;
 6 begin
 7   s2 := ‘‘;
 8   for i := 1 to length(s) do
 9   begin
10     if ((copy(s, i, 1) >= ‘0‘) and (copy(s, i, 1) <= ‘9‘)) or ((copy(s, i, 1) >= ‘a‘) and (copy(s, i, 1) <= ‘f‘))
11       or ((copy(s, i, 1) >= ‘A‘) and (copy(s, i, 1) <= ‘F‘)) then
12     begin
13       s2 := s2 + copy(s, i, 1);
14     end;
15   end;
16   for i := 0 to (length(s2) div 2 - 1) do
17     buf1[i] := char(strtoint(‘$‘ + copy(s2, i * 2 + 1, 2)));
18   comMain.WriteCommData(buf1, (length(s2) div 2));
19   mmMsg.Lines.Add(‘MsgSend[‘ + S + ‘]‘);
20 end;

接收指令

选中控件,添加OnReceiveError事件,代码如下。

技术图片

 1 procedure TMainFrm.comMainReceiveData(Sender: TObject; Buffer: Pointer;
 2   BufferLength: Word);
 3 var
 4   S: string;
 5   I, L: INTEGER;
 6   RBUF: array[0..2048] of BYTE;
 7 begin
 8   Move(Buffer^, pchar(@rbuf)^, BufferLength);
 9   L := BufferLength;
10   for I := 0 to L - 1 do
11   begin
12     S := S + INTTOHEX(RBUF[I], 2);
13   end;
14   mmMsg.Lines.Add(‘MsgReceived[‘ + S + ‘]‘);
15 end;

断开串口连接

comMain.StopComm;
