Device and/or software freeze @100 mV or 50 mV with signal on screen #47

Closed rinntimo closed 2 years ago

rinntimo commented 2 years ago

If I have both signal more than 100 mV AND I set the scale for 100 mV or less the whole thing freezes. BUT if I don't have signal or I have AC-coupling it doesn't freeze. OR if the signal reference point is so high up that the signal will not fit on screen at all when going 100 mV scale - it will not freeze! Might be related to the latest add-on with 100 mV scale? Does not recover unless both restarting the device (USB cable disconnect and reconnect) and restarting the application. Using the latest version 1.1.1-cf13 "About" telling Version 4.0.0 Have tested in both Win10 and Ubuntu.

Please post the full logs (run owon-vds-tiny in a terminal/console or %PROGRAMFILES%\OWON VDS1022\launch.cmd). Does the issue occur with the original OWON software v1.1.1 ? Have you tried to calibrate the device ?

No, the issue is not there with the original 1.1.1. Yes I have calibrated the device several times.

Is it possible to install this software to a RaspBerry Pi? I tried to download and install this install-linux.sh to a RP 4B but it says in the beginning that "Architecture not supported: armhf"

Thanks!

I tracked down the exception. It's related to the measures. It occurs when the voltage offset is not 0 and when the absolute average goes off-screen. I'll fix it in the next release.

Note that there's also an issue with your calibration. Your zero-offset is way off : Yours : 1949 (0x79a) Original: 546 (0x222)

Calibration example (original software):

Calibration of your device (original software):

With the original software, the calibration can be edited by pressing Ctrl+L and tune next to the home button. With this customized version, just press F2.

Is it possible to install this software to a RaspBerry Pi?

Yes it's possible. Just add the following file structure before running the install script :

You'll find the binaries in release 1.0.33-cf12: https://github.com/florentbr/OWON-VDS1022/tree/1.0.33-cf12/lib/linux

You may have to install libusb-compat. The source code for libusbJava.so : https://github.com/florentbr/OWON-VDS1022/raw/master/lib/libusbJava-src.zip

fixed in release 1.1.1-cf14
