DEMO9RS08LA8 Lab
This lab document applies to
DEMO9RS08LA8.
Start each lab with the board powered
ON. Make sure to use only one utility at a
time, as they share the same USB source.

Learn How to Use the
DEMO9RS08LA8 Toolkit Utilities
This lab will show you how to use one of several
graphical utilities in the DEMO9RS08LA8 Toolkit
included with your board. Instructions to download
these utilities to your computer are provided in Step
2 of the Quick Start Guide (DEMORS08LA8QSG.pdf).
In this lab we will use the Logic Analyzer utility that
was installed with the P&E embedded multilink toolkit.
To perform this lab the Quick start application must
be downloaded to the demo board as described in
the Quick start guide. This PC-based utility graphs
the DATA1 and DATA2 signals on the board. For
convenience, if both DATAx jumpers are installed,
DATA1 graphs PTC2 activity and DATA2 graphs PTC3
activity. To graph other microcontroller signals, use
wire jumpers from DATA1 and DATA2 to the respective
signals on the board’s MCU PORT.

Accelerometer Demo
This lab will highlight the performance capability of
the MC9RS08LA8 microcontroller and show how this
microcontroller can easily interface with a sensor. This
lab will also detail how to use another one of several
software utilities included with your board to help
you in your development. Instructions to download
these utilities to your computer were provided in
Step 2 of the Quick Start Guide. The accelerometer
application reads the X, Y and Z axes of the 3-axis
accelerometer on the DEMO9RS08LA8 board using
the microcontroller’s A/D converter. After any reset, it
outputs the raw values of the accelerometer data on
the microcontroller’s serial communication interface.
Pressing the SW1 switch outputs a rolling average
of the raw accelerometer data, and pressing the
SW2 switch outputs a filtered version of the raw
accelerometer data.
