A complete guide to capacitive touch sensors
Chapter 5:
Basics of controllers for capacitive touch sensors
About this chapter
In the previous chapters the readers are introduced to various topics surrounding touch sensor operation and design principles.
In this chapter, readers are introduced to arguably the most important component of capacitive sensing systems: controllers.
In this gentle introduction to capacitive microcontrollers, readers will learn about their role in capacitive sensing systems, the caveats of the controller industry, and will explore the most basic operation principle of controllers for capacitive touch sensors.
Finally, a novel way used by the renowned IC maker STMicroelectronics to support its customers.
