Abstract: MPR03X AN3889
Contextual Info: Freescale Semiconductor Application Note AN3889 Rev 0, 9/2009 MPR121 Capacitance Sensing Settings INTRODUCTION Touch acquisition takes a few different parts of the system in order to detect touch. The first stage of this process is to capture the pad capacitance. Freescale’s MPR121 utilizes the principle that a capacitor holds a fixed amount of charge at a specific electric potential. Both the implementation and the configuration will be described in this application note.
