    How to implement touchpad?

    songfq24_1694131

      Hi, I want to use touchpad or button matrix to detect presence of object on a plane.

         

      The design guide and component datasheet have few information about this.

         

      So how could I set up a button matrix? How to physically connect each sensor widget? Is there any more detailed description about this component?

         

      I attached my project with Tuner. 

         

      PS: I often get I2C communication fail problem, any one knows why is that?

         

       

         

      Thanks!

         

      Good luck.
