Integrating device drivers with LabVIEW

[srini]

I have a device driver written in C for our custom made DAQ card. I want to integrate it with LabVIEW or I want to write a driver for my DAQ card in LabVIEW. Can anyone help me?

Thanx & Regards,
Srini.

Hello Srini

1. If you have a good working driver written in C, you can use it as a "dll" and you can easilly call it from LabVIEW.

2. You can use "Cins" (Code interface node), and call you C code directly from LabVIEW. Read manual for that.

3. If this is a simple DAQ driver, write it from scratch in LabVIEW (but it might be slower that C).

4. Write a IVI driver for your device (simmilar to $1).

good luck

Hello Pawel,
Thanx for your valuable info. I still need some more help.
The acquisition software which I have takes some inputs from the user and then starts acquiring the data. So, I have a doubt whether I can pass these parameters from LabVIEW to the .dll form of my acquisition program. Next is, as you told I can write an IVI driver for my device but I don't know how to do it. Can you help me with some materials or examples on how to write a driver in LabVIEW for a custom made device.

Thanx & Regards,
Srini.
