I need to use a touch key pad (4 key) for my IP67 rated plastic enclosure. I've selected the AT42QT2120 touch sensor IC and designed PCB to operate standalone mode. Unfortunately the IC giving random output and not functioning properly.
If any one has experience with Atmel Qtouch or any touch keypad design, please verify the circuit and PCB and give me your valuable suggestions.

I'm really confused to choose Atmel or Microchip forum to get the help. :roll::roll:
