TIDA-060039

This reference design uses inductive and Hall-effect sensing technologies to provide a human-machine interface. The inductive sensing devices create eight different touch buttons on a seamless surface while the Hall-effect sensor is used to create a magnetic dial that can rotate and be used as an additional button.

Using an inductive sensing touch button provides a robust solution that uses the force of the press to determine a button press. This allows for touch buttons to be used with gloves on while also ignoring environmental factors like dirt or damages to the button surface. The Hall-effect sensor dial creates a contactless rotation that has improved wear and tear over traditional contact-based implementations such as potentiometers or rotary encoders.
