DSO-2150 doesn't show any data

[DanielO]

I have a DSO-2150 and while OpenHantek connects to it OK I don't see any data on the display (even when trigger is set to Wait/Force)

I have tried twiddling many options (eg capture buffer size, time base, etc) but no change.

Can you compile in debug mode? This way all commands send to the scope are printed out.

[DanielO]

Sure.. How? :)
I couldn't see anything in the readme or docs and I am a cmake noob.

[davidgraeff]

cmake -DCMAKE_BUILD_TYPE=Debug on the command line or use QtCreator and select Debug near the bottom in the left pane.

OK I get the following output..

FWIW I am at git hash eaf29e5

If I set trigger to Single and press the play button I get

14:36:26.667: Starting to capture

If I select Wait/Force and press play I get

(repeatedly until I press it again)

Also FWIW if I move the trigger level it sends this command

14:38:33.215: Sending control command b4: ff 00 ff 00 00 00 00 00 00 00 00 00 00 00 00 00 00

but it is always the same (I was expecting the command to vary slightly based on the trigger level)
