AN494 QUICKSENSE COMMUNICATIONS INTERFACE

AN494 Q UICK S E N S E ™ C OMMUNICATIONS I N T E R F A C E 1. Introduction The QuickSense™ Communications Interface (QSCI) is a protocol which allows an MCU running a configurable QSCI Firmware Library to send QuickSense data through one of the MCU's serial peripherals. QuickSense data includes capacitive sensing measurements, infrared proximity measurements, interpreted group values, gestures, and nD pad positions. QuickSense applications, such as the Performance Analysis Tool, use the QSCI pro.
