Could reproduce with last PV release version, could not reproduce with master as of today. With that, I'd guess that either there's some uninitialized variable somewhere or a variable is being overwritten by a broken memory access. |
Created attachment 642 [details] unexpected trace values, and probes dialog How to reproduce: Open pulseview, use the demo device, (lower the sample count to 10k), open the probes dialog (red pin), switch all analog channels' pattern to the next option after their defaults, run. Channel A2 shows data that does not match the configured pattern. The data even starts going wrong after it was correct for an initial period of time? The issue is assumed to be in the demo device driver (unverified).
