1 Introduction

This guide provides the steps necessary to begin

development with a HCS12 family

microcontroller (MCU) using your application

module and/or in conjunction with the Freescale

project board (PBMCUSLK).

This guide is separated into three main sections.

First, the software setup section will assist in

installing the CodeWarrior™ development

tools. Second, the hardware setup section will

step through configuring the project board and

application module. Third, the development

section illustrates how to create, build, and

debug an application.

Refer to the project board user guide,

application module user guide, and

CodeWarrior documentation for more details.

2 Unpack

Open the shipping carton and remove the contents. Locate the packaging list and verify items have been

received from the packaging list.

Inspect both the project board and the application module for damage that may have occurred during

shipping. If damage is found, contact www.freescale.com/support for assistance.

3 Software Setup

The following software installation is a one-time, required procedure per host PC that you intend to use

with the project board and/or application module. After completing the software setup on your host PC,

you can skip the software section on subsequent uses of your project board and/or application module

and begin the hardware setup or development sections.

To install and register CodeWarrior development tools for HCS12(X) Microcontrollers onto a host PC,

complete the instructions found inside the CodeWarrior Development Studio for Freescale HCS12(X)

Microcontrollers case.

Additional tools and training materials for CodeWarrior are available at www.freescale.com

NOTE

Academic Edition development tools are full-featured and not for commercial development. They may

only be licensed to students, faculty, and staff of accredited institutions.

Periodically check http://www.freescale.com/codewarrior for updates and patches to your development

tools. For questions on CodeWarrior development tools, visit http://www.freescale.com/support

4 Hardware Setup

For more information on the Application Module operation, jumper descriptions and settings please

refer to the development board User Guide or visit www.freescale.com\universityprograms for latest

information.

4.1 Configuring the Application Module for independent operation

1) By default, the application module is configured to run independently out of the box. Verify that

all the jumper settings are configured properly on the application module as shown by Figure 1.

2) Plug in the USB cable from the host PC (running CodeWarrior) to the Application Module.

3) Your Done! Proceed to Running your Demonstration application.

4.2.2 Configure the Project Board

Place the project board on a flat and sturdy surface. Ensure sufficient space is available around the

project board to safely construct and test prototyped circuits.

Verify that all the jumper settings are configured properly on the project board as shown by Figure 3.

Highlighted blocks indicate the on or installed position of jumpers. Circles indicate the location on the

project board where the jumpers are located.
