Overview

This evaluation module (EVM) 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.

Features
  • Seamless touch surface
  • Force touch buttons
  • Contactless magnetic dial
  • Push and rotate dial with one device
  • Integrated coordinate rotation digital computer (CORDIC) algorithm
