  1. Hi, I am having a bit of a problem getting my program to work properly. As I have it set up right now, I have a while loop as the outer-most structure. Inside the while loop, I have an event structure (on Value Change). Inside the event structure I have a case structure. The different cases in the case structure correspond to the possible value changes that the event structure detects. Is there any way to constantly repeat events in a certain case structure until the event structure detects a different value (a value change)? I tried putting a while loop inside one of the case structures, but the program just waits in the while loop and ignores any input that is supposed to cause the event structure to detect a value change (and thus execute events inside a different case). I also tried having an external boolean wired to the stop button of the while loop inside a certain case but that did not seem to work either. Any ideas are greatly appreciated. Thanks!
  2. Hi, How can I pull a single element from a 2D array (an array of decimal numbers) and store it in a numeric DBL? Thanks!
  3. Thanks for the help! I will give the notifier a shot.
  4. Hi, I want to pass an integer value from one VI to another VI. What is the best way to go about doing that? Do I want to use Open VI reference? If so, how would I do that? Thanks!
  5. Thanks very much for the help! I obtained the LabVIEW program from Waterloo Labs and everything works great up until the point when I try to output to the data acquisition device. The acquisition device they used in their LabVIEW program was a NI USB-6009. However, the one I have is a PCI-6251. When I try running their program, I get an error saying that the device I'm trying to output to is incompatible and I think it is because they used a different acquisition device. Since I am fairly new to LabVIEW, I am not sure how I can modify the program so that it outputs to the PCI-6251 device instead of trying to output to a USB-6009 acquisition device. I think I have to edit the "Write to Card.vi" but I don't know what changes I need to make. The way I normally use the PCI-6251 device is I right-click in LabVIEW, choose Express --> Output --> DAQ Assist. However, I am having difficulties wiring that device to work with their LabVIEW program. As memoryleak said, their program is located at http://waterloolabs.blogspot.com/. Here's the link to the LabVIEW program they used: http://decibel.ni.co...usic%20Sync.zip Any help would be greatly appreciated! Thanks.
  6. Hi, I am fairly new to LabVIEW and require some assistance. I want to be able to play a song and have LabVIEW detect the beat of the song (the lower frequency spectrum) in realtime. Every time a beat is detected, I want LabVIEW to trigger a switch of some sort. Is this possible? Thanks!
