The DEMO908JL16 board features:
1. An MCU section containing:
 An MC68HC908JL16 microcontroller (in 32-pin SDIP package, already
programmed with a demo application—in addition, you can also use any other pin-
to-pin-compatible device);
 One clock sources: a 9.8304 MHz crystal, selectable via the “OSC ENA” jumper.
2. A power supply section containing:
 A 12 V DC Power Supply Input Connector;
 Power input selection jumpers for selecting the input voltage input source:
o 12 V DC input connector;

3 Software Setup
3.1 Overview
i
Note:before connecting the Demonstration Board to the PC, it is
recommended that you install all of the required software first (see
below), so that the appropriate USB driver will be automatically found by
Windows when you connect the Demonstration Board.
The Demonstration Board requires that both CodeWarrior Development Studio Special Edition
and SofTec Microsystems Additional Components be installed in the host PC.
i
Note: CodeWarrior Development Studio for HC(S)08 must be installed
first.

4 Hardware Setup
4.1 First Connection
The Demonstration Board is connected to a host PC through a USB port. Connection steps
are listed below in the recommended flow order:
1. Install all the required system software as described in the previous section.
2. Make sure the “POWER SEL1” jumper is in the “USB” position.
3. Insert one end of the USB cable into a free USB port.
4. Insert the other end of the USB cable into the USB connector on the Demonstration
Board.
5. The first time the Demonstration Board is connected to the PC, Windows recognizes the
instrument and starts the “Found New Hardware Wizard” procedure, asking you to
specify the driver to use for the instrument. On Windows XP (SP2) the following dialog
box will appear.
Select the “No, not this time” option and click the “Next >” button.
6. The following dialog box will appear.

Click the “Next >” button.
7. Depending on your Windows settings, the following warning may appear.
i
Note: this warning is related to the fact that the USB driver used by
the Demonstration Board is not digitally signed by Microsoft, and
Windows considers it to be potentially malfunctioning or dangerous
for the system. However, you can safely ignore the warning, since
every kind of compatibility/security test has been carried out by
SofTec Microsystems.
Click the “Continue Anyway” button.
8. Windows will install the driver files to your system. At the end of the installation, the
following dialog box will appear.

Click the “Finish” button to exit from the “Found New Hardware Wizard” procedure.
9. The Demonstration Board’s USB driver is now installed on your system.
4.2 Power Supply
The Demonstration Board can be powered in three ways:
 12 V DC input connector;
 USB connector;
 I/O header connector.
Two jumpers (“POWER SEL1” and “POWER SEL2”) specify which power source to use.
These two jumpers work together, as detailed in the table below. Care must be taken in setting
these jumpers appropriately. Please refer to the following table for details.

5 Operating Modes
5.1 Overview
The Demonstration Board can work in two modes: “standalone” mode and “host” mode.
5.2 Standalone Mode
In standalone mode, no PC connection is required. The microcontroller is factory programmed
with a sample application.
To run the built-in example:
 Ensure that the “OSC ENA”, “PTD5 ENA”, “PTD4 ENA”, “PTD3 ENA”, “PTA1 ENA” and
“PTA0 ENA” jumpers are inserted.
 Ensure that all of the accelerometer enable jumpers (“PDT2”, “PTD1”, “PTD0”, “PTA7”,
“PTA5” and “PTA4”) are inserted.
 Power on the Demonstration Board through either the 12 V DC plug-in power supply or
the 28-pin I/O Header connector, and make sure that the “POWER SEL1” and “POWER
SEL2” jumpers select the appropriate power source (see chapter “4.2 Power Supply” for
details).
 The green “POWER” LED on the board should turn on.
 Press the “SW0” push-button. Then, by rotating the potentiometer, you affect the results
of the A/D conversion, which in turn varies the blinking frequency of the “LED1” and
“LED2” LEDs.
 Press the “SW1” push-button. Then, by rotating the board around its x, y or z axes, you
affect the accelerometer reading along that axis, and the “LED1” and “LED2” LEDs turn
on, off or blink depending on the board’s position.
5.3 Host Mode
In host mode the program execution is controlled by the host PC through the “USB” connector.
You can use the PC to debug the application by, for example, executing the program step by
step and watching how the microcontroller registers vary, using the provided CodeWarrior
Development Studio.

Operating Modes
Page 16
i
Note: all of the HC08 family devices feature a monitor code resident in
ROM which, through a serial communication line, allows the programming
and the in-circuit debugging of the user application. The monitor code is
executed in “monitor mode”; the user application is executed in “user
mode”. To enter the monitor mode some microcontroller lines must be
properly driver (for further details please refer to the microcontroller’s data
sheet).
The USB TO MON08 INTERFACE section groups the circuitry needed to
generate the required signals to enter the monitor mode and
communicate with the host PC’s USB port. In particular, to enter the
monitor mode, the “USB TO MON08 INTERFACE” circuitry:
 Generates a high-level voltage signal (VTST) on the IRQ pin of the
microcontroller;
 Generates a high-level voltage and an appropriate reset signal on
the RST pin of the microcontroller;
 Drives the microcontroller’s VDD on and off, with specific timing, in
order to enter the monitor mode;
 Handles a single-wire, bi-directional serial communication line on a
specific pin of the microcontroller.
To work in host mode (using the built-in USB to MON08 interface):
 Make sure that all of the jumpers in the “USB to MON08” section are inserted.
 Make sure that the “POWER SEL1” jumper is in the “USB” position.
 Connect the host PC to the board through the provided USB cable.

6 Application Tutorial
6.1 Overview
This section will provide a step-by-step guide on how to launch your first project and get
started with the CodeWarrior for HC(S)08 user interface.
6.2 Step-by-Step Tutorial
The sample application is the same as the one described in the “Standalone Mode” section
above.
1. Ensure that the Demonstration Board is connected to the PC (via the USB cable) and
that the board is powered.
2. Make sure that all of the Demonstration Board jumpers are set to their factory position
(see chapter “7.1 Jumpers” for details)
3. Start CodeWarrior for HC(S)08 Development Studio by selecting it in the Windows Start
menu.
4. From the CodeWarrior main menu, choose “File > Open”. Select the “Demo.mcp”
workspace file that is located under the “\Program Files\SofTec Microsystems\
DEMO908JL16\CodeWarrior Examples\C\Demo” directory. Click “Open”. The Project
Window will open.
5. The C code of this example is contained in the “main.c” file. Double click on it to open
it.
6. From the main menu, choose “Project > Debug”. This will compile the source code,
generate an executable file and download it to the demo board.
7. A new debugger environment will open. From the main menu, choose “Run >
Start/Continue”. The program will be executed in real-time.
8. From the main menu, choose “Run > Halt”. The program execution will stop. The next
instruction to be executed is highlighted in the Source window.
9. From the main menu, choose “Run > Single Step”. The instruction highlighted in the
Source window will be executed, and the program execution will be stopped immediately
after.
10. From the main menu, choose “Run > Start/Continue”. The application will restart from
where it was previously stopped.
Congratulations! You have successfully completed this tutorial! You can continue to
experiment with the CodeWarrior user interface and discover by yourself its potentialities. For
an in-depth guide of all of the user interface features, select “Help > CodeWarrior Help” from
CodeWarrior Development Studio’s main menu.
