Problem with detecting changes using PCI-6527 with NI-DAQmx

[kovalenkov]

Thanks a million times. One problem solved, one to go. I still get a callback function call approx. every 4 seconds, even though no input has been changed. Any ideas?

When I am using Traditional NI-Daq, everything works fine.

That one I'm not so sure about. Try posting this problem along with a description of your system's hardware, the data that it is returning, and what types of signals you are feeding your board on the Digital I/O forum where it would be seen by people who know a lot more about your DAQ card and its driver software than I do.
