GPIB

[sunnyvale]

Hi
We are 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(microchip) 16C77 MCU as the master controller of the equipment.
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 th
ere .How we can develop program for GPIB using this package.
5. Who will help in designing the same

Please help me .
Thanks in advance.
regards
Prasad"

Hello Prasad,

I think the Register Level Programming page will be helpful for you. You can refer to the Application notes to get an idea of how the TNT 4882 chip is used with other microcontrollers. It will also help to look at the Data sheet for the TNT 4882.

The TNT is compatible with any microcontroller or processor that allows you to do reads/writes. Any microcontroller
that can address an 8-bit chip should be able to use the TNT. Some microcontrollers have interrupt capability which the
TNT can use, and some do not (in which case they can use the programmed I/O feature of the TNT).

You will need to use the ESP. You will need a C based compiler for the PIC. The ESP package will help
you program the chip..but you will need to know specifics of
your PIC.

If you have any questions, please contact us via email by going to www.ni.com/ask and selecting "Email an Engineer".

Good Luck,

HI Kim,
If we are developing the program (firmware for PIC) using assembly do we need to use ESP package?I think ESP package is helpful to develop the c program only if we are using C compiler for PIC.Am i right? SO is there any need of programing the GPIB chip?
Please let me about your ideas regaring this.
