Camera Error Number

Technical Programming
1

Hey Guys!!

I’ve been trying to get the camera up and running, but I’ve been getting an error when I call GetImage. The error number is 166204. I’ve searched high and low for what camera error numbers mean and I haven’t been able to find anything. So do any of you know what this error means, and possibly how to fix it? Thanks.

I assume you are using LV. I can’t find anything on that code either. Just to verify, make sure you can ping the Camera. Also, do you get this error code when you Open the Camera Reference as well?

I can’t find an error for that number. The LV WPI errors are all in the -44000 range. It could possibly be referring to a notifier or a lower level LV resource that isn’t being used properly, but that number doesn’t show up as one.

Can you attach the code that produces the error? A picture of the code might reveal the issue, but a VI is even better.

Hey Guys!!

Thanks for the responses. I am actually using WindRiver this year. I found in the FRCError.h header file that my error number is an initialization error, but I’m still not really sure why I’m getting it. I copied my source code in the bottom of this post, so maybe that will help.
