CPU runs 100% when logging with DAQmx using card 6229

[Minnet]

Hi!

When I start a logging using DAQmx Analog Input  the computer CPU runs 100%. This causes the problem that the computer locks and the subsequent steps in the program are left without computer CPU recourse. After the logging is compleet, 1750 samples/10 channels at 250Hz, the program runs on, but the loggfile is at that point useles.

I have instaled LV 7.1.1 and am using DAQ 7.4.

Anyone that recognizes this problem?

Regards,

Idriz

hi there,

are you really sure you're using DAQmx 7.4? i ask because 7.3 had some reasonable problems with CPU usage. see the software section in MAX to get the version number. to be sure i suggest to download DAQmx 7.5 and reinstall it over LabVIEW 7.1.1.

have you tried to run some of the examples shipped with LabVIEW? if they also don't work i suggest to post some code so we can have a look.

best regards

chris

Hello Idriz!

I just wanted to respond here as well so you know that we have read your post on this very forum. Still waiting for an answer from the US and after that I will forward that information to you.

Hello!

I sent you the example through e-mail but it might be interesting for others as well to see how you can handle CPU usage and DAQmx.
