About
DEMO9S08QE32 Labs
These labs will show you how to get the
most out of your DEMOQE toolkit. 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
DEMOQE Toolkit Utilities
This lab will show you how to use one of several
graphical utilities in the DEMOQE Toolkit included
with your board. Instructions to download these
utilities to your computer are provided in Step 2 of
the Quick Start Guide (DEMOS08QE32QSG.pdf).
Running the Quick Start Application that came pre-
loaded in the microcontroller’s on-chip flash memory,
we will now use the DEMOQE Logic Analyzer utility.
This PC-based utility graphs the IN0 and IN1 signals
on the board. For convenience, if both J11 jumpers
are installed, IN0 graphs PTC0 activity and IN1 graphs
PTC1 activity. To graph other microcontroller signals,
use wire jumpers from IN0 and IN1 to the respective
signals on the board’s MCU PORT.
1. Make sure that the Quick Start Application is running.
2. Launch DEMOQE Logic Analyzer utility from the start
3. In utility, click on the “Open DEMOQE and Graph Pins”
4. Click button labeled “PTA2.” This will cause a fixed duty
5. Rotate the potentiometer W1. This will change the duty
6. Click on “Close Port” button when finished.
For more information on DEMOQE Toolkit, read the
board user manual (DEMO9S08QE32UM.pdf) included
on DVD under “DEMO9S08QE32
User Manual.” For new and upgraded utilities to the
