Hi there !

   

This is a kind of consultation for those who know about Capsense.

   

I would need to build a kind of "matt"  to detect multitouch.

   

It shoul be  10 row for 15 column.

   

Each of those" Keys" should be arround 1 square inch.

   

I am wondering it is possible build such " matt" with Capsense and there will not be intolerable amount of interference among keys.

   

It should be considered that  the key form a surface of 15" long for 10" wide.

   

 

   

Thank you very much for any help about that.

   

Best regards all of you.

A different approach would be a resistive touch-foil. Have a look at this AppNote: www.cypress.com/

   

Button sizes and cable would fit better than a CapSense keypad.

 Hi,

   

Do you mean to build touch pad or just matrix of buttons ? In touch pads, finger position is calculated and in matrix buttons, which button is touched is detected.
