Hantek 6022BE 20MHz USB DSO
gf:
The 2nd image looks like a problem with the Graphics Driver. The program attempts to use a GLSL 1.5 shader, but the Graphics Driver (or the GPU) installed on the PC does not support this GLSL version.

Yes, I tried it on another machine that supports OpenGL 3.3 and it works fine.
Sadly there is nothing I can do about the laptop, it already has the latest drivers ;-(

Hi,
Usage: openhantek/OpenHantek [options]
Options:
-h, --help Displays this help.
-v, --version Displays version information.
-d, --demoMode Demo mode without scope HW
-e, --useGLES Use OpenGL ES instead of OpenGL
-i, --international Show the international interface, do not translate
you can try the option -e (or --useGLES) to switch the graphics driver

EDIT:
If OpenGL reports its version >= 3.2 then OH choses GL SL (shader language) version 1.50, otherwise version 1.20 is used. (My development laptop reports e.g. "2.1 Mesa 18.3.6", so it uses 1.20)
Read more about the versions:
https://github.com/OpenHantek/openhantek/issues/221
I've added the command line options "--useGLSL120" and "--useGLSL150" to override the automatic version detection. It is available starting with OH version 3.1.1-rc1 that I just checked in - please check.

Thank you - that (-e) worked like a charm :-)
Brilliant! It is much better than the Hantek software.
I dont know if this is the place for suggestions ...
I would suggest putting the command line switches in the manual along with the keyboard shortcuts (I found cursor up/down by accident (it alters the vertical scale)).
Perhaps cursor left/right should alter the horizontal scale, and shift up/down moved the trace up and down the screen.
I would personally also find it very useful if the mouse scroll wheel "zoomed" the trace - just a thought :-)
Very impressed,
Dave

Hi Dave,
The up/down buttons change the last selected pull-down field, in your case the V/div section. If you select the trigger source, this entry will change with up/down. This is not an intrinsic behavior of OH6022, but is controlled on the window manager level (windows as well as linux).
Nevertheless, I will put your mousewheel zoom scrolling proposal into my collection of future improvements.
Martin
P.S.:

I am reading this forum irregularly, the safest way to reach me is to open an issue at github.
