Introduction
DEMOQE128 is a cost-effective
board targeting quick microcontroller
evaluation. The board includes two
plug-in daughter cards to highlight
the ease of migration between the
Flexis
ColdFire V1
The board also includes a power
terminal to measure the ultra-low
power consumption of the Flexis
QE128 devices.
This quick start guide is designed
to get you ready to develop your
application on the QE128 within
minutes. Please take a look at
the DEMOQE128 Labs document
(DEMOQE128LAB) to learn more
about the key benefits that QE128
gives your application.

that run on your computer and help speed up your development. These utilities take development
beyond the hardware and interact with the target microcontroller over the same USB multilink
reference design on the board that allows you to debug using CodeWarrior. Best of all, you can
debug your microcontroller in CodeWarrior while simultaneously using one of the following utilities:
Logic Analyzer, Serial Grapher, Terminal Window and Accelerometer Demo Grapher.

Quick Start Application
Now that you have successfully completed the software and hardware setup, test your board by
running the Quick Start Application pre-loaded in the microcontroller’s on-chip flash memory.
The programmed application samples the microcontroller’s general-purpose input pins connected to
push buttons to 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. Last, 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.
2. Press push buttons labeled PTA2, PTA3, PTD2 and PTD3. A different tone

Additional DEMOQE
Toolkit Applications
In addition to the Quick Start Application
and Logic Analyzer Utility, the DEMOQE
Resources on the Breaking Bit
Boundaries DVD-ROM features other
toolkit applications that work with
the DEMOQE128 board. One such
application is featured below.
Accelerometer Demo
Application
This graphing application will graph data
from the serial port or virtual serial port
on the DEMOQE board. The state of
the on-board three-axis accelerometer
is sampled by the microcontroller-based
serial accelerometer demonstration
code using on-chip A/D converter
channels. This data is converted into
ASCII characters and sent out the
serial port of the DEMOQE board. The
data is then graphed by the PC-based
graphing application for the user to
view. This application may be used to
graph any data as long as the data is
formatted properly.
Both the MCU-based demonstration
code and the PC-based graphing
application may be downloaded from
www.pemicro.com/fixedlinks/
demoQEtoolkit.html.
Virtual Serial Port
The DEMOQE128 board also has the
capability of implementing a virtual serial
port on the PC. This allows the PC to
send and receive serial data via the serial
communication pins of P&E’s Embedded
Multilink design. Using jumpers J6
and J7, this virtual serial port may be
configured to connect to the SCI port
on the QE128 processor.
