1.1 Introduction
This paper describes the next generation of design of a Wireless Sensing Triple Axis Reference design
(ZSTAR3), a demo for wireless demonstration of the 3-axes accelerometers MMA7450L
(RD3172MMA7450L) and MMA7360L (RD3172MMA7360L) sensors from Freescale. This demo is
succesor of previous Freescale demo ZSTAR and its fully compatible with it.Demois build on new
generation of Freescale parts and brings some extended functionalities.
The reference design will enable you to see how Freescale's accelerometers can add additional
functionality to applications in various industries. The accelerometer measurements can be grouped into 6
sensing functions - Fall, Tilt, Motion, Positioning, Shock and Vibration - for multifunctional applications.
The RD3172MMA7450L / RD3172MMA7360L development tool offers robust wireless communication
using the powerful, easy-to-use 2.4GHz frequency transceiver and microcontroller in one package
MC13213. Without any changes on board can be made with pin to pin compatibility allowing
implementation of the MC13214 for ZigBeeTM wireless applications.
Only Sensor board was updated completely, as receiver is still used USB stick from previous generation
of ZSTAR, but new software was developed that can support all new functionalities
