Capacitive Touch BoosterPack

Capacitive Touch BoosterPack

The 430BOOST-SENSE1 Capacitive Touch BoosterPack is the first extension module for the MSPEXP430G2 MSP430 LaunchPad Value Line Development Kit (see Figure 1). Extension modules such as this one, designed specifically for the LaunchPad, are called BoosterPacks, and each features an application example for one of the MSP430 Value Line devices. The BoosterPacks can be connected to the MSP-EXP430G2 with both 10-pin male headers (included in MSP-EXP430G2 kit) soldered onto the board and, therefore, use all available pins on the MSP430G2452 Value Line device.

The Capacitive Touch BoosterPack features the new MSP430G2xx2 devices, which are capable of driving up to 16 capacitive-touch enabled I/O pins. The included MSP430G2452 device allows for low-cost capacitive-sensing and approximation-sensing applications without the use of any external components. The BoosterPack includes a capacitive-touch board and an MSP420G2452 device that is preprogrammed with a demo application. The user experience application demonstrates capacitive touch as standalone feature by showing the user interaction directly with the onboard LEDs, by a GUI, or by an application example on a Microsoft Windows PC

• Nine LEDs giving instant feedback to user interaction
• Six capacitive-touch areas (a button, a 4-element wheel, and a proximity sensor)
• One preprogrammed MSP430G2452 device
• The Capacitive Touch User Experience consists of three projects: The firmware application that can operate in stand-alone mode (LaunchPad Capacitive Touch BoosterPack Firmware Demo) A processing GUI that displays the information from the LaunchPad Capacitive Touch BoosterPack visually (LaunchPad Capacitive Touch BoosterPack GUI Demo) A Visual Studio program that uses the LaunchPad Capacitive Touch BoosterPack input to control media in Windows (MediaPad).
