Is there a way to get more capacitive touch inputs?

[Lola]

Both the capacitive touch library and the driver (which is better ?) are using the analog inputs. There are only 8 of them , and we need 10 at least buttons.

Is there a way to "cheat" ? I need different buttons where you can also detect when I touch 2 at once.

The docs says you can connect 2 pads for the same analog pin which seems impossible knowing the basics of hardware and capacitance ( how one pin differentiate between to shorted pins?) infocenter.nordicsemi.com/index.jsp

Thanks.

You can always use an analog mux. This is the same way they mux the ADC pins internally on the nRF. You need to pay attention to your minimum dwell time but even so you can easily add more inputs.

Not sure how but I guess for production that wouldn't be so accurate.

Actually I am missing just another button ( I need 9 ) , I am trying to think how can I connect it with one of the 8 AIN or maybe all of them to get another behaviour.
