I just got an ebay DSLogic Pro working in sigrok Pulseview using the information on the wiki. I'm on Windows 7, using a nightly build from about a week ago (0.4.0-git-8b9056d).
I'm seeing some strange behavior which could be a hardware issue, but feels to me more like software or firmware. When I look at a signal (on any channel), the trace is low when the signal is low, but it toggles at Nyquist when the signal is high. That is, for any sample rate Fs chosen from the dropdown menu, during high periods, the recorded trace is a square wave at Fs/2. I am using the threshold setting for 3.3v logic, which matches the device under test. (If I select the threshold for 5v logic, the traces are constant low, as expected.) Also, I've debugged the same circuit with a Salae so I know it's working properly. Has anyone seen this before? Should I try the DSLogic version of sigrok instead?
