Description

This TI Design demonstrates an ultra-low power implementation of capacitive touch inputs for various human machine interface (HMI) requirements in consumer, industrial & other applications. This solution leverages unique features available in the MSP430 Value Line microcontroller that enables developers to interface capacitive touch elements directly to a microcontroller I/O 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 complete hardware and software reference design to enable developers to quickly and easily replace any physical button with a capacitive touch element. This combination provides a cost effective solution for adding capacitive touch to consumer electronics, point of sales machines, and devices that have a physical button.

Features
  • Capacitive touch elements:
    • Scroll Wheel
    • Button
    • Proximity Sensor
  • 9 on-board LEDs for instant feedback
  • Timer-based UART communication enables interface to PC
  • Open source GUI
  • Fully supported by the MSP430 Capacitive Touch Sense Library"
