When I first turn on the DSO there is a demo purple waveform. Is there a way to hide or modify it? I do not have an SD card in the DSO. Thanks.
Reflash your NANO with Paul software. It comes without demo waveform.
ESP: Thanks for putting it on the Google code project!
That makes a nice place to have all the downloads. Much easier than scavenging the forum 
We should have done this much earlier.
