Well, it works fine, BUT: If the screen is off, the touch panel works. (I see it through the tv out) Just when I turn on the screen, the touch stop working!
I've checking ground loops, pins, short circuits... nothing.
Since USB touchscreen board is feeded by the USB 5v. and ground pins, it works even if the rest of the screen electronic is off. Due to this I can't understand why when it lites, it stops working. Maybe a hi-voltage interference?
Has anybody had the same problem? Has anybody any idea about how can I get rid of this? Tonight I have a presentation of my prototipe...
Thanks a lot,
