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.

3.4 LAB 3: Measure Performance between 8-Bit and 32-Bit

This lab will highlight the performance differences between the 8-bit and 32bit QE128 microcontrollers and demonstrate how these microcontrollers can 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.

Setup demo:

1. Open CodeWarrior for Microcontrollers. From the Windows Start menu, locate it under “Programs>Freescale CodeWarrior>CW for Microcontroller V6.0>CodeWarrior IDE” path.
