Basics of controllers for capacitive touch sensors
Contents of chapter 5
5.1 The role of the controller in a capacitive touch system
Learn about how a controller transforms the analogue signal emitted by the touch sensor, into a digital one, that can be used by the rest of the system.
5.2 The touch controller industry, its caveats, and the operational principle of the capacitive touch controller
Familiarize yourself with the caveats of the controller industry and explore the most basic operation principle of controllers for capacitive touch sensors.
