1 INTRODUCTION

1.1 Overview

The DEMO9S08SC4 is a low-cost development system designed for demonstrating, evaluating, and debugging the Freescale MC9S08SC4 microcontroller. P&E’s Embedded Multilink circuitry on the DEMO9S08SC4 board allows the processor on the DEMO9S08SC4 to be debugged and programmed via USB from the PC. In addition, the demo board can be powered using the USB bus.

1.2 Package Contents

The DEMO9S08SC4 package includes the following items:

• DEMO9S08SC4 Demo board

• USB Cable

• Freescale Warranty Card

1.3 Supported Devices

2 HARDWARE FEATURES

The DEMO9S08SC4 is a demonstration and development system for Freescale’s MC9S08SC4 microcontroller. Application development is quick and easy using P&E’s Embedded Multilink circuitry and the included software tools and examples. An optional BDM port is provided to allow use of an external BDM interface such as P&E’s Cyclone PRO automated programmer or USB Multilink. The USB Multilink is functionally comparable to the DEMO9S08SC4’s Embedded Multilink circuitry.

Note: The DEMO board’s onboard Embedded Multilink circuitry is intended to

function with the onboard processor and any daughter cards that may be included. It cannot be used to communicate with other devices.

2.2 On-Board Logic Analyzer

The DEMO9S08SC4 board has a built-in 2-channel logic analyzer which may be used to display captured data in real-time on a host PC. The logic analyzer channels (IN0/IN1) are connected to the PTA1 and PTB5 signals on the DEMO9S08SC4 board by default via the J14 jumpers. The channels may be connected to any of the processor pins by wire jumpers (not included).

The DEMO9S08SC4 Logic Analyzer Utility, included in the Embedded Multilink Toolkit on the accompanying CD-ROM, displays the logic analyzer signals on a PC.

2.3 On-Board Virtual Serial Port

The DEMO9S08SC4 board has a built-in virtual serial port which may be connected to the SC4 processor’s SCI RXD/TXD. This allows certain PC applications to be able to connect in a serial fashion to the microcontroller without the actual use of serial port hardware.

The Terminal Window Utility, included in the Embedded Multilink Toolkit on the accompanying CD-ROM, is a generic serial port utility which works with the virtual serial port or actual serial port hardware.

3 SYSTEM SETUP

3.1 Overview

P&E’s Embedded Multilink driver is required to operate the DEMO9S08SC4 using a PC. The Embedded Multilink driver should be installed with the CodeWarrior Development Studio software or from the DEMO9S08SC4 Resources in the CD-ROM before the PC is connected to the DEMO9S08SC4.

3.2 Operating System Requirements

The following are the resources required to run the CodeWarrior Development Studio and the DEMO9S08SC4:

• A PC-compatible system running Windows 2000, Windows XP, or Windows Vista

• 128MB of available system RAM, and 1GB of available hard disk

space

• A CD-ROM drive for software installation

• A USB port

3.3 Software Setup

3.3.1 Installing CodeWarrior Development Studio

To install the CodeWarrior Development Studio, insert the CodeWarrior CD into your computer’s CD-ROM drive. A start-up window will automatically appear. Select CodeWarrior Installation and follow the on-screen instructions.

3.3.2 Installing P&E Resources

Use the DEMO9S08SC4 Resources CD-ROM to access and install P&E resources for the DEMO9S08SC4. These materials are not required for operation. The support materials contained on the DEMO9S08SC4 Resources CD-ROM are listed in Section 1.4 - Recommended Materials On

DEMO9S08SC4 Resources CD.

3.4 Quick Startup

Only a few steps are required to get the DEMO9S08SC4 up and running:

Step 1. If you do not have CodeWarrior Development Studio version 6.0

installed on your computer, please install it using the accompanying CD-ROM. Additional information regarding CodeWarrior can be found at www.freescale.com.

Step 2. Remove the DEMO9S08SC4 demonstration board from its anti-

static pouch.

Step 3. Connect the USB cable from your computer to the

DEMO9S08SC4 demonstration board. Depending on your operating system, you may need to follow steps to install the USB driver from the DEMO9S08SC4 Resources CD-ROM. Once the USB cable is connected properly the green USB LED on the DEMO9S08SC4 should illuminate.

Step 4. Turn on the DEMO9S08SC4 power switch (K1). The red Power

LED should illuminate.

Step 5. [Will be updated with Quick Start Guide code operations]

Step 6. [Will be updated with DEMO code] Optionally, you may run the

Logic Analyzer Application available in the Embedded Multilink toolkit on the CD. This PC-based application graphs the IN0 and IN1 signals on the DEMO9S08SC4 board. If both J14 jumpers are installed, IN0 shows PTA1 and IN1 shows PTB5. Push button S1 and turn the potentiometer to change these signals. This application may also be found at:
