Embedded systems (PIC based): We are looking to upgrade our GPIB controller chip from Ines iGPIB7210 to a more "mainstream" chip and are interested in NI's offerings.

[James Alston]

Ines provides a library of ANSI C source to drive their GPIB chip from any suitable processor (as do ComputerBoards). Do NI have a source code library for their driver chips? BTW it doesn't need GPIB "Controller" capability. The uP controlling the GPIB chip is a Microchip PIC18C452.

Mr. Alston,

All of National Instruments' technical resources on the GPIB ASIC's can be found at:
http://www.ni.com/support/gpib/reg_prog.htm

We also have a basic shell developed called the ESP-488. There is a link to this distribution from the above website. It was developed for use with the TNT4882 GPIB chip. This kit and the manual for the TNT4882 are a powerful set of tools for developing embedded GPIB applications.

Hi Mr James,
Thanks for your question ..We are also planning to have GPIB interface for our equipment .Again we are new to the interface design .For our equipment we dont need controller capability.I think Ni TNT 488.2 T/L is suitable for our application .But we are stuck with this ...Our equipment has a PIC 16c77 MCU.
If you can help regarding the procedures to be followed for having this GPIB interface that will be great!!!
I have some doubts regarding this.
1. How we can use the TNT 488.2 chip in our equipment board.
2. How we can controll this GPIB chip Is it is done by PIC controller?
3. Is above PIC is compatible with TNT 488.2 T/L.
4.Do we need to program the GPIB chip.I know that there is a devoper kit ESP-488 package is there .How we can
develop program for GPIB using this package.
5. Who will help in designing the same

Please help me .
Thanks in advance.
