Delphi - 采用第三方控件TMS、SPComm开发串口调试助手

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。

 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;
