AN494 - QUICKSENSE COMMUNICATIONS INTERFACE

Key Features

  • like transfer types and modes. In QSCI the host interacts with the device through an extensive command set. The device parses the command and transmits or modifies the requested QuickSense variables. QSCI Lite offers a memory-map based architecture which supports a smaller command set than QSCI. The majority of the interaction in QSCI Lite is through address read and write commands. The device provides the host with the addresses of QuickSense variables. The host decides what data is relevant an.

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 protocol to communicate to QuickSense kits like the QuickSense Front Panel and the IRSliderEK. This document covers the capabilities of QSCI and the protocol specifications. It assumes the reader is familiar with the QuickSense Firmware API.
