I have a requirement that I thought would be SIMPLE, but can't get it to work. I have a 9205 card in a little 9174 cDAQ USB chassis. My *intended* behavior is to wait (block) at the DAQmx Trigger/Start Analog Edge on, say channel ai1, until I get a falling edge thru, say, -0.050V. So I have a little vi (that contains 2 parallel loops) that I want to sit & wait for the trigger to be satisifed. I'm doing "routine" voltage measurements in another AI loop on a different channel. I want this vi to run separately from my "routine" voltage measurements because I want the app to respond "
I have a problem I was hoping you might be able to help me figure out. I need to be able to create 6 analog output channels that will have separate data files loaded into them. These channels will be started individually in a timed sequence. I am having trouble getting the analog DAQ tasks created. LabVIEW is complaining when I try to set them up as individual tasks in the same routine. I used a for loop on an array of data files and an array of channel names. The error code is suggesting that I set the channels up under one task. But the problem with that is that I donâ€™t know how
