I have six PXI-6561 cards monitoring 72 digital lines, 12 per card. I want to run a VI for up to 1-hour, using Match Pattern (or similar) to grab a waveform for rising edge events on any digital line. Not all digital lines will see a rising edge, and some may see 10,000 rising edge events. Sample Rate 2MHz, record length 10-points is fine, as I'm only interested in the arrival time of each pulse.
I've successfully coded for one 6561 Card, using “pattern not matching” xxxx000000000000 (only 12 lines from 16 used on each card).
This works okay because the card sees an event, however, when I move to 6-cards, the code returns errors because the number of events specified has not been reached for every card. How can I code for any number of events? I'd like GUI to have real-time count of the number of events detected for each line, but can’t see a property node for this.
I’ve attached my code for a single card as .llb.
My data output format will be a list of events detailing the Time-of-Arrival from t0:
Line-1 TOA 0.0000005
Line-1 TOA 0.0001050
Line-23 TOA 0.0000010
Line-71 TOA 0.0000500 etc… .etc….
My "Add Attachment" link does not open a file open window, will try to add code tomorrow after a reboot. Font size, smileys etc dissapeared too ??
