DEMOQE128 board. The faster the PC is, the more rapid and smooth the
data display in these utilities will be.
For more information on the DEMOQE Toolkit, see the board user manual
(DEMOQE128UM.pdf) included in the DVD under “DEMOQE128 >
DEMOQE128 User Manual” in the navigation panel on the left side of the
DVD menu. For new and upgraded utilities to the DEMOQE Toolkit visit http://
www.pemicro.com/fixedlinks/demoQEtoolkit.html.
STEP 3: CONNECT DEMOQE128 BOARD TO COMPUTER
USB driver installation is a one-time required step that requires
CodeWarrior installation first.
1. Remove the board from the anti-static pouch. The green 8-bit
MC9S08QE128 daughter card will be mounted on the base board.
2. Connect the provided USB cable from a free USB port on your com-
puter to the USB connector on the board. If a HUB is used, it must be
self-powered.
3. The operating system will recognize your board as new hardware and
will prompt you to install the USB drivers. Choose the recommended
option to install the software automatically. (USB drivers for your
board were pre-loaded in CodeWarrior installation.)
4. Follow the on-screen instructions until all USB driver installations are
complete. The green USB LED on the board should illuminate.

DEMOQE128 User Manual 9
STEP 4: TEST BOARD BY RUNNING QUICK START APPLICATION
Now that you have successfully completed the software and hardware setup,
test your board by interacting with the Quick Start Application that is pre-
loaded in the microcontroller’s on-chip flash memory.
The programmed application samples the microcontroller’s general purpose
input pins. These pins are connected to push buttons and perform two
actions. The first action is to illuminate the respective LED with either a
general purpose output pin or a pulse-width modulated signal pin. The second
action is to play a different tone per push button on the speaker, using a
pulse-width modulated signal programmed at different frequencies. The
application samples the potentiometer using the microcontroller’s analog-to-
digital converter and uses the result to vary the light intensity of two LEDs by
changing their pulse-width modulated signal’s duty cycle.
1. Turn the SYSTEM POWER switch to the ON position. The red
POWER LED will illuminate and the application will start automati-
cally.
2. Press push buttons labeled PTA2, PTA3, PTD2, and PTD3. A differ-
ent tone will be emitted from speaker when each push button is
pressed, and the corresponding LEDs labeled PTC1, PTC2, PTC3,
and PTC4 will illuminate.
3. Rotate the potentiometer (W1) to vary the light intensity of the LEDs
labeled PTC0 and PTC5.
4. Now that your board is functional, try out the provided labs in
DEMOQE128 Labs section to learn more about the Flexis QE128
microcontrollers and other features included with your board.
3.2 LAB 1: Learn How to use DEMOQE Toolkit Utilities
This lab will show you how to use one of several graphical utilities in
DEMOQE Toolkit included with your board. Instructions to download these
utilities to your computer are provided in Step 2 of the Section 3.1 - Quick
Start Guide. Make sure to use only one utility at a time, as the utilities all
share the same USB resource. The toolkit utilities may be used at the same

10 DEMOQE128 User Manual
time that an application is being debugged and programmed on the
DEMOQE128 board from within CodeWarrior.
With the Quick Start Application (which comes pre-loaded in the
microcontroller’s on-chip flash memory) running we will 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. If you would like to graph other
microcontroller signals, you can use wire jumpers from IN0 and IN1 to the
respective signals on the board’s MCU PORT.
1. Make sure the board is powered ON and that the Quick Start Applica-
tion is running.
2. Open the DEMOQE Logic Analyzer utility from within the
DEMOQE_Toolkit folder by double-clicking on the LogicAnalyzer.exe
file.
3. In the utility, click on the “Open DEMOQE and Graph Pins” button to
begin graphing IN0 and IN1. These signals will be continually
graphed at a sampling rate of 10Khz.
Figure 3-4: DEMOQE Logic Analyzer

DEMOQE128 User Manual 11
4. Press the push button labeled PTA2. This will cause a fixed duty
cycle pulse-width modulation signal to be output on the PTC1 pin.
The PTC1 waveform is shown on analyzer channel IN1.
5. Rotate the potentiometer W1. This will change the duty cycle of the
variable pulse-width modulation signal output on the PTC0 pin. The
PTC0 waveform is shown on analyzer channel IN0.
6. Click on the “Close Port” button when you are finished using the util-
ity.
Some of the toolkit applications capture and display data from the
DEMOQE128 board. The faster the PC is, the more rapid and smooth the
data display in these utilities will be.
Note that the above image is shown with the IN0 channel zoomed in. Each
analyzer channel has several features including the ability to be zoomed and
paused. For more information on DEMOQE Toolkit, see the board user
manual (DEMOQE128UM.pdf) included in the DVD under “DEMOQE128 >
DEMOQE128 User Manual” in the navigation panel on the left side of DVD
menu. For the latest DEMOQE Toolkit utilities, please visit http://

the same USB resource.
The Accelerometer Application reads the X, Y, and Z axes of the 3-axis
accelerometer on the DEMOQE board using the microcontroller’s analog to
digital converter. It outputs a processed version of the accelerometer data on
the microcontroller’s serial communication interface. This processed data is a
rolling average of the raw accelerometer data, or a filtered version of the raw
accelerometer data, depending on the selected mode. The application in this
lab will output the data as 16-bit integer values to highlight the data
processing capabilities of the 32-bit ColdFire V1. The application also
displays the cycle count (“C”), which is the number of MCU bus cycles
required for the CPU to process the last 16 accelerometer readings for the
selected mode.
