Hi Martin,

Thanks a lot for you efforts, OpenHantek6022 is great!

I started adding support for the Sainsmart DDS120 to OpenHantek6022 (I was part of the group behind OpenBuudai, see https://www.eevblog.com/forum/testgear/sainsmart-dds120-usb-oscilloscope-(buudai-bm102) ) and got it somewhat working on my Macbook. I am using the sigrok firmware.
It still crashes from time to time when switching sample rates too quickly (?) and support for switching between AC & DC coupling is missing, but otherwise it's working quite well (better than the included SW for sure and better than OpenBuudai as well IMHO). Are you interested in a pull request?

Regards,

Markus

Hi Markus,

Yes, I'm very interested in your PR!
The crash is a known regression introduced with v2.15 (this version was withdrawn after  issue report #26. But the change from 2.15 to 2.16 (released yesterday) is not to big...
The AC coupling was removed due to missing HW support in the Hantek device and to get free space in the voltage docks for the 1X / 10X settings. But lets have a look how big the differences are. I think it would also be possible to adapt my FW - but let's go step by step.

You are right, 2.16 seems to fix the crash  :-+

Just created the PR. Please test if this doesn't break anything for the 6022...
