    How to implement touchpad?


      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?






      Good luck.
