I have just received and fired up my Xprotolab, purchased via Australian Robotics. Brilliant little gadget. Well done!
Being an oldie, I do find the screen as I expected - cute but small. PC software seems like a good idea.
I'm trying to do all of my hobby work under Linux, but I see the PC software is for Windows
I also note there is an Android app, Oscilloscope Pro, but it's not open source and I have no Android devices.
I wonder if the XoScope project on SourceForge could be adapted for the Xprotolab. Yes? No?
