TIDM-LPBP-CAPTOUCH

This reference design demonstrates an ultra-low power implementation of capacitive-touch inputs for various human machine interface (HMI) requirements in consumer, industrial and other applications. This deisgn leverages unique features available in the MSP430 value-line microcontroller that enables you to interface capacitive-touch elements directly to a microcontroller input/output pin without the need for external or additional passive components. The capacitive touch BoosterPack features several capacitive touch elements including a scroll wheel, button and proximity sensors. When paired with the MSP430 LaunchPad, this combination provides a hardware and software reference design to enable you to quickly and easily replace any physical button with a capacitive-touch element. This combination provides cost effectiveness for adding capacitive touch to consumer electronics, point-of-sales machines and devices that have a physical button.
