ZSTAR3 Wireless Sensing Triple Axis Reference design
Introduction
2.1 Introduction
The Wireless Sensing Triple Axis Reference design (ZSTAR3) has been designed as a new generation of
the previous ZSTAR (RD3152MMA7260Q) demo. A 2.4GHz radio-frequency (RF) link is also used in
this new demo and its based on new solution modem and microcontroler in one package MC13213
family.And it’s used for connection from the Sensor to PC, allowing the visualization of key accelerometer
applications as in previous demo.
Figure 2-1. ZSTAR3 sensor board
The demo consists of the two boards(new one and old one with new software):
• Sensor Board (or remote board) it is new board designed to demonstrating Freescale new 3-axes
accelerometers solution for digital(MMA7450L) and analogue(MMA7360L) sensing
accelerometric data and 2.4GHz RF modem with HCS08 microcontroler in one packege solution
as easy design for remote sensors.
• USB stick, with the MC13191 RF front-end, and the HC08 family MCHC908JW32 for the USB
communication. This board are used from older ZSTAR demo with new software.
Both sides communicate over the RF medium utilizing the freely available software lightly modified stack
SMAC from Freescale.
