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 computer 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.
8 DEMOQE128 User Manual
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 preloaded 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-todigital 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 automatically.
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
DEMOQE128 User Manual 9
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 Application 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
10 DEMOQE128 User Manual
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://

interface easily with an external sensor. You will also see how to use another
one of several software utilities included with your board. Instructions to
download these utilities to your computer are provided in Step 2 of this Quick
Start Guide. Make sure to use only one utility at a time, as the utilities share
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.

V1 CPU over the 8-bit S08 CPU. In the data averaging and data filtering
modes, a considerable amount of 16-bit and 32-bit math is required. The S08
CPU is capable of performing these tasks, but it requires a substantial portion
of its bandwidth. In contrast, the ColdFire V1 CPU performs the same tasks
with only a very small portion of its bandwidth. With Flexis QE128
microcontrollers, you can pick and choose the CPU that best matches your
performance needs.

microcontroller which is plugged into the DEMOQE board.
DEMOQE128 User Manual 29
Figure 6-4: Accelererometer Demo Application
The data that is graphed may come from either the PC serial port or the virtual
serial port on the DEMOQE board. The serial port of the microcontroller on
the DEMOQE board is routed to either serial port hardware or the virtual COM
port based upon the setting of jumpers J6 and J7. To properly configure
accelerometer and potentiometer resources on the DEMOQE evaluation
board, please make sure that these headers are populated with jumpers in
the following manner: J16 (Z/PTA7 -populated, Y/PTA6 –populated, Y/PTC7 populated, X/PTA1 –populated); J14 (set to 0); J16 (set to 0); J15 (set to 1);
J21 (PTA0 –populated, PTC6 –populated).
To start using this application, please choose COM or virtual USB COM
settings from the drop-down Port menu. By doing so, you are specifying the
port on the evaluation board that will be used for transmitting captured

6.5 DEMOQE Serial Grapher Application
This PC-based application is a more generalized version of the accelerometer
demo application. It may be used with the microcontroller based serial
accelerometer application or customer microcontroller code which transmits
data in the correct format. The serial graphing utility allows incoming data on
the PC serial port, or one of P&E’s virtual serial ports, to be automatically
graphed in time or displayed upon a series of bar graphs. The virtual serial
port exists on several of P&E’s embedded USB multilink designs including the
DEMOQE board.
To start using this application, please choose COM or virtual USB COM
settings from the drop-down Port menu. By doing so, you are specifying the
port on the evaluation board that will be used for transmitting captured
accelerometer data via a COM or USB serial port. Please make sure that the
jumpers on headers J6 and J7 are set accordingly. Prior to starting serial data
capture, please specify the Baud setting to reflect the parameter at which your
serial communication interface is operating. Once your port settings are
configured, please plug a USB or DB9 serial cable into the evaluation board
and click on the Open Serial Port and Start Demo button. The graphing of
data can be paused and the scale on the X and Y axes can be changed via a
tool bar located in the top right corner of the DEMOQE Serial Grapher
Application.
This PC-based application is included on the DVD-ROM that accompanys the
DEMOQE and may also be found at:
http://www.pemicro.com/fixedlinks/demoQEtoolkit.html.
All data to be displayed must be in hexadecimal format. The data can be
accepted and displayed either as incoming byte values ($00-$FF) or word
values ($0000-$FFFF). The data format indicates whether the data is byte or
word data. The graphical components automatically size their range
depending upon the incoming data.
DEMOQE128 User Manual 31
6.5.1 Visual Components
The Bar Graph has four separate bars A, B, C, and D. On each bar a
percentage value is displayed which indicates the current value relative to the
full range. A byte value of $7F (max is $FF) would show up as approximately
50% as would a word value of $7FFF (max is $FFFF). As can be seen in the
data formatting section, all four bars must be written at the same time. The
bars are shown here:
Figure 6-5: Serial Grapher Bar Graph
The graphing component shows four waveforms X, Y, Z, and W. The
magnitude axis either has a range of $00-$FF (if byte values are incoming on
the serial port) or $0000-$FFFF (if word values are incoming). Each new set
of values which comes through the serial port is added to the far right side of
the graph and the rest of the data values move to the left. The vertical axis
displays the incoming data as the magnitude of each waveform, and the
horizontal axis displays the number of samples. The graph has a limited size,
so older samples will eventually fall off the left part of the graph. As can be
seen in Section 6.5.2 - Data Format, each incoming data command affecting
the graphing component must have new data for all four waveforms. An
example graph is shown here:
32 DEMOQE128 User Manual
Figure 6-6: Serial Grapher Graphing Component
6.5.2 Data Format
The data format is broken into two sections depending upon whether the
incoming data is in byte format or word format.
6.5.2.1 Byte Formatted Data
There are two commands which may be accepted. Both commands must end
in the special characters #$0D and #$0A which are CR (carriage return) and
LF (line feed). The accepted commands are:
WnnZnnYnnXnn
The nn values are 00-FF and correspond in order to the data displayed on the
following graph lines : W, Z, Y, X.
AnnBnnCnnDnn
The nn values are 00-FF and correspond in order to the data displayed on the
following bar graphs lines : A, B, C, D.
6.5.2.2 Word Formatted Data
There are three commands which may be accepted. All commands must end
DEMOQE128 User Manual 33
in the special characters #$0D and #$0A which are CR (carriage return) and
LF (line feed). The accepted commands are:
nnnn,nnnn,nnnn,nnnn
The nnnn values are 0000-FFFF and correspond in order to the data
displayed on both the graph and bar graphs as follows: X/A, Y/B, Z/C, W/D.
nnnn:nnnn:nnnn:nnnn
The nnnn values are 0000-FFFF and correspond in order to the data
displayed the graphing component as follows: X, Y, Z, W.
nnnn=nnnn=nnnn=nnnn
The nnnn values are 0000-FFFF and correspond in order to the data
displayed on the bar graph component as follows: A, B, C, D.
7 DEMONSTRATION MICROCONTROLLER APPLICATIONS
The following microcontroller applications are designed to run on the QE128
processors.
7.1 Quick Start Application

tone and illuminate a different LED for each of the buttons which may be
pressed on the DEMOQE128 board. The potentiometer controls the intensity
of two LEDs on the DEMOQE128 board, via PWM signals. This application
comes pre-programmed into the memory of the QE128 processor.
Usage of this application can be seen in the Section 3.1 - Quick Start Guide
of the manual.
34 DEMOQE128 User Manual
7.2 Serial Accelerometer Application
This microcontroller application samples the state of the on-board three-axis
accelerometer using on-chip A/D converter channels. This data is converted
into ASCII characters and sent out using the serial pins of the QE128
processor. These serial pins may be connected to either serial port hardware
or to P&E’s virtual serial port (which is part of the Embedded Multilink design).
This connection is controlled by jumpers J6 and J7.
P&E has two PC-based DEMOQE Toolkit applications which allow the serial
port data generated by this application to be graphed. These are documented
in Section 6.4 - DEMOQE Accelerometer Demo Application and Section
6.5 - DEMOQE Serial Grapher Application.
Usage of this application is documented in the Section 3.4 - LAB 3: Measure
Performance between 8-Bit and 32-Bit.
8 JUMPER SETTINGS
8.1 System Power
The QE128 processor may obtain its power from either the on-board

11 TROUBLESHOOTING
11.1 DEMOQE128 Is Undetected
Q: The connection assistant indicates that my DEMOQE128 is undetected
even though I have connected the hardware to my USB port. What should I
do?
A: The connection assistant, which displays in either Codewarrior or P&E’s
development software, is a dialog which allows the user to connect to the
DEMOQE128 hardware. If this dialog indicates that the DEMOQE128
hardware is not connected to the PC, the first step is to make sure that the
DEMOQE128 hardware is connected to the PC via a USB 2.0 high-speed
cable. If it is connected, unplug and then plug in the USB cable on the
DEMOQE128 board and click refresh in the connection assistant. If the
hardware still does not show up, try the following remedies:
(A) Re-Enable the USB driver
DEMOQE128 User Manual 49
If you connected the DEMOQE128 interface prior to installing P&E’s
Embedded Multilink drivers, Windows will not have been able to find the
appropriate driver and may have disabled the device. The DEMOQE128
board shows up in Window’s device manager as a “P&E Multilink,” since it
contains P&E’s Embedded Multilink circuitry. If you unplug and then plug in
the device, Windows will automatically disable it even if you have installed the
drivers. To force windows to try to load the driver again, perform the following
steps while the DEMOQE128 interface is connected to the computer:
1. Open the Control Panel (Start Button->Settings->Control Panel)
2. Double Click the "System" Icon
3. Select the "Hardware" tab
4. Click the "Device Manager" Button
5. The "P&E Multilink" device will be shown with an exclamation mark
next to it. Double-click this device.
6. Click the "Reinstall Driver…" button and follow the dialog instructions
to have Windows automatically install the driver.
(B) Re-Install the USB driver
If the Multilink device does not show up in the device manager, use the driver
installation utility located in the DEMOQE Resouces on the DVD-ROM. After
driver installation, unplug the DEMOQE128 from the PC and reboot the PC.
When the reboot has completed, connect the interface to the PC with the USB
2.0 cable. Run the software again to see if the interface is now detected.
If you have an error attempting to install the drivers, please view the
installation troubleshooting FAQ on P&E’s website at:
http://www.pemicro.com/faqs/faq_view.cfm?id=89.
(C) Test for installation of the USB driver files
To test the driver installation, use the driver test utility in the DEMOQE
Resources of the DVD-ROM to make sure all files were properly installed.
This may give some indication of what the problem is.
(D) Using a USB Hub
The DEMOQE128 is a high-power USB device. If a USB Hub is used, it must
be a self-powered hub (i.e., with its own power supply). If the Hub is not selfpowered the DEMOQE128 will not work. In general, USB ports located
directly on the PC are high-power (self-powered) ports.
