Overview
This document will guide you through all the steps necessary to begin development on an HCS12 Family
microcontroller unit (MCU) using your MCUSLK. The software setup section will assist you install the
Metrowerks’ CodeWarrior software and necessary software to support your MCU Project Board – 2. The
hardware setup section will walk you through configuring the MCU Project Board – 2 for use with the
MC9S12C32 MCU application module (Axiom’s CSM12C32). The development section will show you
how to create, build, and debug your application. Refer to the MCU Project Board – 2 user guide,
MC9S12C32 MCU application module user guide and Metrowerks’ CodeWarrior documentation for
details.

Software Setup
Software Setup
The following software installation is a one-time, required procedure per host PC that you intend to use
with the MCU Project Board – 2. After completing the software setup section on your host PC, you can
then skip the software section on subsequent uses of your project board and begin with the hardware
setup or development sections.
1. To install and register CodeWarrior development tools for HC(S)12 MCUs onto a host PC, follow
the instructions outlined in sections A, B, and C of the CodeWarrior Development Studio for
Freescale 68HC(S)12 Microcontrollers quick start pamphlet found inside the supplied 3-cd case
labeled CodeWarrior Development Studio for HC(S)08 Special Edition and HC(S)12 Special
Edition. Make sure to request the special edition license when registering.1The special edition
license version of CodeWarrior is necessary for developing applications for the MC9S12C32 MCU
application module board.
2. Install a CodeWarrior service patch labeled “CW12_V3_1_ICD12_USB2_0_Sim_patch.exe”
located in the Service Pack CD found inside the supplied 3-cd case labeled CodeWarrior
Development Studio for HC(S)08 Special Edition and HC(S)12 Special Edition. The patch is
located under the E:\HC(S)12\CW12_V3_1\ directory in the Service Pack CD. Install by double-
clicking on the file and by following the on-screen instructions.
NOTE
The CW12_V3_1_ICD12_USB2_0_Sim_patch.exe is REQUIRED for the
USB multilink pod on the MCU Project Board – 2 to function with the
Metrowerks CodeWarrior development tools and must be installed prior to
the hardware setup section. Other patches included on the Service Pack
CD are recommended if developing an application on a HC(S)12
microcontroller other than the MC9S12C32.
NOTE
Periodically check the corresponding development tool product page for
patches and updates. For questions on CodeWarrior development tools,
contact [email protected]
1. Registering will email you instructions for how to acquire the special
edition license. After you acquire the special edition license, place it in the
root CodeWarrior directory. If you encounter problems with registration, you
can acquire your special edition license online at
http://www.metrowerks.com/MW/Develop/Embedded/HC12/Downloads.

Unpack
1. Open the shipping carton and remove the contents. Verify that all packing list items have been
received.
2. Inspect both the MCU Project Board – 2 and the MC9S12C32 MCU application module for any
damage that may have occurred during shipping. If damage is found, contact the manufacturer at
[email protected] for assistance.
Configuring the MCU Project Board – 2
1. To begin, place the MCU Project Board – 2 on a flat sturdy surface. Ensure sufficient space is
available around the project board to safely construct and test prototyped circuits.
2. Verify that all the factory default jumper settings are configured properly on the MCU Project
Board – 2 as shown by Figure 1. Highlighted blocks indicate the “on” or “installed” position of
jumpers. Circles indicate the location on the project board where the jumpers are located. Table 1
summarizes the default state for the jumper settings. Please refer to MCU Project Board – 2 User
Guide for more details and alternative configurations.

Creating and Building a Project in CodeWarrior Environment
After properly installing and registering the CodeWarrior development tools as described in the Software
Setup section, and completing the MCU Project Board – 2 configuration as described in the Hardware
Setup section, you can now begin to develop your application for a target microcontroller. This section will
create and build a project under the CodeWarrior for HC(S)12 development tool platform.
NOTE
The instructions below are slightly different from the steps described in the
quick start pamphlet included in the CodeWarrior for HC(S)12 development
tools CD case. The instructions below are adjusted for the MCUSLK and
MC9S12C32 development module.
1. Launch the CodeWarrior IDE
a. Select:Start>Programs>MetrowerksCodeWarrior>CW12V3.1;amenu
will appear
b. Select: CodeWarrior IDE; IDE will start and a CodeWarrior window will appear
2. Create a new project
a. From IDE main menu bar, select: File> New; a new window will appear (see Figure 7)
Figure 7. New Window
b. Select: “HC(S)12 New Project Wizard”
c. In the “Project name” text box, type the name you want to give the project (IDE automatically
adds .mcp extension when it creates project)
d. In the “Location” text box, set location where you want the project to be created
e. Click “OK” — the first page of the new project wizard will appear (see Figure 8a)
