The MSP430FR2633 is a low-power microcontroller with multiple GPIOs and capacitive touch pins. This project creates a circuit that supports a custom capacitive touch panel with LED and haptic feedback.
This article presents some basic cap-sense circuit configurations and discusses how to deal with low- and high-frequency noise.
