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 HCS12(X) must be installed
first.
3.2 Host System Requirements
The Demonstration Board is controlled by CodeWarrior Development Studio. The following
hardware and software are required to run the CodeWarrior user interface together with the
Demonstration Board:
 A 200-MHz (or higher) PC compatible system running Windows 98, Windows 2000 or
Windows XP;
 128 MB of available system RAM plus 1 GB of available hard disk space;
 A USB port;
 CD-ROM drive for installation.
3.3 Installing CodeWarrior Development Studio
To install the CodeWarrior Development Studio Special Edition, insert the CodeWarrior CD-
ROM into your computer’s CD-ROM drive. A startup window will automatically appear. Follow
the on-screen instructions.

Software Setup
3.4 Installing SofTec Microsystems Additional
Components
The SofTec Microsystems “System Software” CD-ROM contains other required components to
your hard drive. These components include:
 SofTec Microsystems DLL for DEMO9S12PFAME support;
 Examples;
 Demonstration Board’s user’s manual;
 Demonstration Board’s schematic;
 Additional documentation.
To install the required components, do the following:
1. Insert the SofTec Microsystems “System Software” CD-ROM into your computer’s CD-
ROM drive. A startup window will automatically appear.
2. Choose “Install Instrument Software” from the main menu.
3. Click on the “Copy SofTec Microsystems DLL to \CodeWarrior for HCS12
V4.7\Prog\gdi” option. An Explorer window will open. Copy the “SofTec_BDM12.dll”
file to your PC in the “\CodeWarrior for HC12 V4.7\Prog\gdi” folder, relative to the
CodeWarrior installation path.
4. Click on the “Copy examples for CodeWarrior for HCS12 V.4.7” option. An Explorer
window will open. Copy the “DEMO9S12PFAME” folder to your PC, in a location of your
choice. These are the examples specific for the demonstration board, and will be used
later in the step-by-step tutorial.
i
Note: to install the Additional Components on Windows 2000 or Windows
XP, you must log in as Administrator.

4 Hardware Setup
4.1 First Connection
The Demonstration Board connects 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 SEL” 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.
Page 11

Hardware Setup
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.
Page 12

DEMO9S12PFAME User's Manual
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.
The “POWER SEL” jumper allows you to power the board through either the 12 V DC input
connector or the USB connector.
When using the I/O header connector, its pin 1 is connected to the VDD line of the carrier
board through the “VAUX ENA” jumper.
Page 13

DEMO9S12PFAME User's Manual
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:
1. Ensure that the light sensor “ENA” jumper is inserted.
2. Ensure that all of the “LED ENA” jumpers are inserted.
3. Ensure that the two push-button “ENA” jumpers are inserted.
4. Ensure that the “RS-232/LIN SEL” jumper selects the “RS-232” position.
5. Ensure that the “POWER SEL” jumper selects the “UNREG” position.
6. Power on the Demonstration Board through the 12 V DC plug-in power supply.
7. The green “POWER” LED on the board should turn on.
8. Press the “PP0” push-button. Rotate the potentiometer. Its value will be shown on the
LEDs.
9. Press the "PP1" push-button. The output of the light sensor will be displayed on the
LEDs.
10. The value of the potentiometer or the light sensor is also sent to the RS-232 port (baud
rate = 9600, data bits = 8, parity = N, stop bits = 1).
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.
Page 15

Operating Modes
i
Note: all MCUs in the S12 family contain a single-wire background debug
interface which supports in-circuit programming of on-chip non-volatile
memory. This system does not interfere with normal application
resources. It does not use any user memory or locations in the memory
map. The Background Debug Module (BDM) uses a single-wire
communication interface (via the BKGD line) to allow non-intrusive access
to target system memory and registers.
To work in host mode (using the built-in USB to BDM interface):
 Make sure that both the “RESET#” and “BKGD” jumpers are inserted.
 Make sure that the “POWER SEL” 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 HCS12(X) 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 on.
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 by selecting it in the Windows Start menu.
4. From the CodeWarrior main menu, choose “File > Open” and choose the
“DEMO9S12PFAME\C\Demo\Demo.mcp” file. This is the board example you copied
from the SofTec Microsystems “System Software” CD-ROM.
5. Click “Open”. The Project window will open.
6. The C code of this example is contained in the “main.c” file. Double click on it to open
it.
7. From the main menu, choose “Project > Debug”. This will compile the source code,
generate an executable file and download it to the demo board.
8. A new debugger environment will open. From the main menu, choose “Run >
Start/Continue”. The program will be executed in real-time.
9. From the main menu, choose “Run > Halt”. The program execution will stop. The next
instruction to be executed is highlighted in the Source window.
10. 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.
11. 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.
