AN52678 describes how to measure orientation and tilt with PSoC® 1 using the KXSC7/KXTC9 triaxial analog accelerometer. Additional information is provided to help you interface other triaxial accelerometers to PSoC 1 devices.

Introduction

Accelerometers are electromechanical devices that change output based on dynamic (force from an external source) and static acceleration (earth’s gravitational force: “g”). This facilitates measurement of orientation, tilt, inclination, vibration, rotation, and other parameters. Different types of accelerometers and algorithms are suited for each of these parameters. This application note shows the interface with Programmable System-on-Chip™ (PSoC) to obtain the orientation and tilt with respect to earth (static acceleration). You can use this interface technique with other accelerometers and algorithms to suit your application.
