Re : IMAQ FOR USB Problems

[Barto]

Hi everybody.

I know taht the subject has been related several times, but I don't find the answers for my problem.

I have a USB camera Logitech;

I'm using Windows XP SP2 french.

Labview 8.2 and NI Vision assistant 8.2.

Whit the driver given by the manufacturer of the webcam, it didn't appeared in MAX, so I made a driver with NI-VISA and now, the USB Camera is visible in the devices in MAX.

I have installed NI IMAQ FOR USB (found on the site) but the vi's don't appear in the functions palette after a reboot, and when I try to open it manually, I have a message saying that the conversion of the vi's didn't work.

When I try the examples vi's in IMAQ, there's no one who works. There is a error message:

"Error occured in IMAQ-Init.vi

Interface not found."

So my question is:

How could I simply acquire data from my webcam?

What is the procedure?

Did I miss files to copy on my computer? Any driver?

Please help!

Thanks.

Hi
You can copy the llb in user.lib, all the vi will appear in I:O instrument >> driver instrument.
You have example shipped with the librairy, it works fine.

There is an other solution , managing by activeX the program sent with your webcam by the manufacturer.

Thanks

I copied the llb into the good directory, and I got the vi's, but the problem is that I havn't the examples and that when I don't know why my webcam is not recognized.

Any idea?
