About DEMOQE 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.

Familiarize yourself with these buttons:

AccelerometerDemo running on MC9S08QE8 in data

averaging mode. Bar graph ‘C’ highlights the bus cycles

required to average the last 16 readings of the 3 axes.

The value in the 4th column in the terminal window is the

number of bus cycles in hex.

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 (DEMOS08QE8QSG.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 (DEMO9S08QE8UM.pdf) included

on DVD under “DEMO9S08QE8

User Manual.” For new and upgraded utilities to the

Using the Low-Power Modes

This lab will demonstrate usage of three of the

MC9S08QE8’s low-power modes: LPRun, stop2 and

stop3. The lab uses the Terminal Window application

from the DEMOQE Toolkit Utilities to display the

elapsed time since the program started in

hours:minutes:seconds. The software has four modes

of operation:

1. normal run mode

2. low-power run mode (LPRun)

3. stop3 with the external oscillator running

4. stop2 with the external oscillator running

The different modes are selected with the switches

on the DEMOQE board. The display will update every

5 seconds with the elapsed time since the last reset.

In the LPRun mode, the display is not updated, but

the total count is continuously updated. In addition,

pressing the RESET button will toggle the clock gating

open and shut. The MCU current can be measured in

the different modes by replacing the shunt on jumper

J24 (labeled on the bottom of the DEMOQE board)

with a current meter. Lowest power consumption is

achieved by removing jumpers from accelerometer

(J13-J16), potentiometer (J21) and LED circuitry (J9).

For this lab to operate correctly, the IIC pullup jumpers

(J20) must be removed.

Measure Performance of the

MC9S08QE8 with Accelerometer Demo

This lab will highlight the performance capability of the

MC9S08QE8 microcontroller. It 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 DEMOQE

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 PTA3 switch outputs a rolling

average of the raw accelerometer data, and pressing

the PTA2 switch outputs a filtered version of the raw

accelerometer data. For this lab to operate correctly,

the IIC pullup jumpers (J20) must be removed.
