I've been trying (unsuccessfully) to set up a Digital Discovery to trigger when multiple conditions are met. I've tried using the Pulse options but I can't see a way of linking multiple signals so I guess I need to use a script. Basically, I want to detect a 960ns pulse on DIN6 and, after it has been detected, trigger if any of four signals (DIN 1, 2, 4 or 5) fails to transition high to low within +/- 30ms. Could someone point me to a sample script that I can use as a starting point to do this?

Thanks @attila, all working now. Turned out the FPGA only outputs signals when a particular register is set properly (doh!). After I confirmed the DD was working properly (using your test setup above), is was easy to backtrack to why there was no data coming in. Thanks

Hi I'm running a Digital Discovery from a Linux (Mint 20) PC, 64bit Linux running on an i7. I'm trying to monitor a few digital signals from an FPGA but I never see any transitions in Waveforms. For now I'd just settle for seeing one of the lines go high but they're all just flat-lined (and I know there is activity). I've set the digital voltages to 1.8V (in Supplies) and messed around with the sample rate but nothing ever shows up. First question, does the DD support 1.8V logic? (if not I won't waste any more of anyone's time) Is there an easy way to test the device (it's never been used - may be faulty) that doesn't require me building anything? I'm working from home (remote project) so I don't have a ton of equipment handy If the DD can handle 1.8V logic, am I setting it up correctly? Thanks in advance DAQ-small.dwf3work I've attached my config file if it's any use
