I am currently using Joulescope UI version 0.8.16 and driver version 0.8.14. While doing measurements the UI freezes when I change the current too fast upward. It seems to work sometimes on another computer, both computers with Windows 10. When it freezes the USB indicator in the bottom right corner turns red. Only when I get the current back to where it was stable it turns back to green and the measurement continues. In the log file I get the following warning:
WARNING:2020-06-22 10:22:01,958:main.py:1407:joulescope_ui.main:status RED: d_sample_id=0, d_sample_missing_count=0
I assume it has to do with the computer. I tried to this also with only the UI open and no other USB connected - still freezing.
