Communication with GPIB Card

I am using a GP-IB card with delphi 10. I cant figure out how to "set up" the install so I can get delphi to communicate with the card.

Card is http://www.contec.com/product.php?id=1146

What are the steps for getting it to communicate with outside device? What dll file do I add? What is a basic 1 button program that would just check if GPIB card was installed?

I hope I am asking this right, I could really use an into to how to do this communication.

Solution

  • I don't want to install this software, but see that help contains functions' description like this

    GpTalkEx
Operation            Transmits data. When transmits binary data by VB, use GpTalkExBinary..

Format                (C)

DWORD Srlen, Ret;
DWORD * Cmd;
char * Srbuf;

Ret = GpTalkEx(Cmd, &Srlen, Srbuf);

    You have to find what DLL do these functions refer to - search in .bas or .h header files. Then translate header file to Delphi (.pas variant might be provided by producer) like this (static import variant)

    function GpTalkEx(Cmd: DWord; var Srlen: DWord; Srbuf: PChar):DWord; 
                  cdecl; external 'GPIB.dll'; // I've used arbitrary name

    and use functions in your program.
