Hi,
I purchased a dso150 kit a while back and it worked fine untill a few days ago. Now it seems the central knob can only turn down, on certain functions. So on voltage and sec/div it can only turn down, so I am constantly on 5mv and 10 us. but on trigger state it reaches SING and won't loop over, untill I turn the other way on the knob, so it is registering direction. The voltage selector for trigger can also only move down.
I opened it up but don't see anything broken. Can somebody please tell me what is the problem? It seems to be software but a reset doesn't fix it.
Thanks

Re: DSO150 can only move down
I checked all connections of the rotary encoder with the FAQ guide and everything seems to match perfectly.
Re: DSO150 rotary encoder only moves down on certain functio
So, it sounds like it's a software problem? Or is there another unchecked potential issue source?
Re: DSO150 rotary encoder only moves down on certain functio
Yes it does look like software but I didn't do anything to the flash, one day it just booted up like this. I'm not sure if I can easily reflash the soc, I don't have an st link or anything, just a uart chip.
