Read foot control click

[marcoapolinario]

Hi guys!

My name is Marco i'm delphi developer.

I did download of 2 programs in site http://www.lvr.com/hidpage.htm, both are sample
about HID, SimpleHIDWrite3 and HIDTestSource.

At SimpleHIDWrite when i click on foot control(VEC) it return
the codes in HEX:
RD 00 02 00
RD 00 01 00
RD 00 04 00

How can i do to get this information? because the SimpleHIDWrite hasn't code
avaliable

Thanks

If you're asking how to request the data in code, the data is in Input reports. I believe Robert Marquardt's code shows how to request Input reports in Delphi. The report descriptor defines the contents of the reports.

Jan thanks for answer.

But, how i did say before the software SimpleHIDWrite hasn't source available.
see the application's print (user: medicoweb password: medico5683)

The other code HidTest that has source, but i'm able to get the Input reports like
the image above, i tried but didn't get,see the application's print (user: medicoweb password: medico5683)

It looks like the device has multiple HID interfaces. After finding the first HID, continue to search for additional HIDs. Each will use a different handle.

(I changed your hyperlinks to plain text so the password box appears only if you click the link.)

Have you same sample about? in Delphi?

I'm try the code without success

procedure THidViewMainForm.HidCtlDeviceData(HidDev: TJvHidDevice;
  ReportID: Byte; const Data: Pointer; Size: Word);
Var
   i  : Integer;
   Str,teste,teste2,teste3: String;

Begin
   For I := 1 To Size - 1 Do
       Str := Str + Char( Cardinal( PChar( Data )[ I ] ) );
   teste:=ConvStr(Data,8);
   teste2:=ByteToHex(ReportID);

   Memo1.Lines.Add( 'RECIBIDO : ' + Str +''+ teste+''+teste2);
   beep;
  CopyMemory(@ReceivedData, Data, Size);
  teste3:=bintostr(ReceivedData);
  Memo1.Lines.Add('Got Data!');

End;

I'm really lost...

Maybe you could start with Robert's HidTest application (my site has the source code for that) and modify it to do what you need.

I haven't used Delphi in a very long time so can't be of much help on Delphi programming.
