Custom Hardware with LabVIEW OR LW/CVI

[Vishal]

Hi all,
We have a custom made DAQ card (ISA one). We are using "C language" to communicate with this card . Now we want to use LabVIEW for the same purpose. Is there any protocols we have to follow to do this? or any additional steps we have to take for this? Please guide us.
I am new to this thing. So please bare with me.

Thnaking you.

First of all you have to understand the protocol of communication with your card. In most cases you have to specify the I/O base address and then write and read some data in the memory near this address.
I think you can start from the C program. Read it and clearly understand what it does. Then try to rewrite this program in LabVIEW. If you cann't make some operations in LV then you have to write C DLL and use it in LV. The most simple way is to organize all functions from your C code into DLL and then to call them from LV. But first of all you have to know what your C program realy does to communicate with card.

Good luck.
