Controller to be Controller in Charge.

[zepp]

I get a error with a Qimaging lab view example

Error 1 occurred at Driver fault at C:\Archivos de programa\National Instruments\LabVIEW 7.1\user.lib\qcam\QCam.llb\QCAM Copy.vi

Possible reason(s):

LabVIEW:  An input parameter is invalid.
---
NI-488:  Command requires GPIB Controller to be Controller in Charge.

what does error mean and how is it fixed.i am using 7.1

thanks

Since you aren't using GPIB, the first possible error is the one you should look at - "an input parameter is invalid". Double check the values of all of your controls to see if they are correct.

there does not seem to be an invalid input there is no error in the vi. would it always show up if there was.
i am new to labview.

i just moved the grap setup into a while loop and it work . not sure why but i wouldn't question it.

thanks for your help. it is nice to see people willing to share there knowledge with noobies like me.

I am having this same exact issue with 'driver fault', I can't figure out why the qimaging examples don't run.  I am sequencing everything perfectly.

Hello. I have a problem with "Write To Measurement File" block. In example vi it works fine, but when i try to use it in my Real-Time application, it doesn't even create the file no matter what the input signal is (real or simulated). I also get the warning about GPIB controller if i check "Ask user to choose file". Can someone help with this?

Hi Sami,

If I was you I would start a new thread for this question, by clicking on the New Message option.

You are more likely to get an answer this way.
