TI powered Design of a Gesture-Based Capacitive Touch Speaker Interface Reference Design demonstrates an ultra-lowpower panel for controlling speaker systems. The design uses an MSP430™ microcontroller (MCU) with CapTIvate™ technology for recognizing capacitive touch events. Using a self-capacitance configuration of sensors to detect proximity, tap, drag, and swipe gestures, this design can enhance a speaker system’s interface and improve the user experience. The MSP430FR2633 MCU drives all capacitive sensing functionality.
