oh shit I’m stupid, bad translation only… I thinked that you used some kind of polyester layer (film) over the PCB, where keys are … sorry ;-)

Hi, please can you tell me, what exactly is the “polyester film 220 nF” ? You inspired me so I’m working now on something like this, but with QT1081.
Thanks rochne

Hi,
I´m working on a 9button-touch-pannel with a qt160 DIP-version. I used the basic circuit from qprox. The output pins have always 0VDC.-I don´t get it running. Could you put your circuit online?

I’m thinking the electrical traces embedded in the lcd would interfere with the sensors. The datasheet goes on and on about how a simple led can interfere with the sensing.
