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?
