1-uA Capacitive Grip Detection Based on MSP430 Microcontrollers (Rev. B)

This application report discusses how to design a simple and ultra low-power grip detector BoosterPack for the MSP430 LaunchPad™. The PINOSC feature in every msp430G2xx2 and msp430G2xx3 device makes it possible to eliminate all the external components when implementing a capacitive touch design. All the components used in the grip detector such as capacitive sensors LEDs are all integrate
