Overview
Alaboratory experience is vital for us to be able to start programming the microcontroller and to be able to really understand how it works and how to apply it in embedded system designs. This module shows the student how to enter a C program into the CodeWarrior® integrated development environment and then to simulate its execution and search for and find a program error.

Learning Objectives
Inthis module you will start to learn about the CodeWarrior® programming environment. You will see how to start the system and enter a program to be run with the simulator, and you will explore some of the features of the simulator.

Success Criteria
At the end of this module you will be able to compile a C program and to run and debug it with the CodeWarrior True-Time Simulator.Prerequisites
You must have some C or other high-level language programming experience.

Using CodeWarrior®
1. Launch the CodeWarrior IDE. a. 2. 3. From the Windows desktop, click Start > Programs > Freescale CodeWarrior > CW for Microcontrollers V6.0 > CodeWarrior IDE.

Create New Project. Microcontrollers New Project. a. Device and Connection (i)Select the derivative you would like to use: Flexis > QE Family MC9S08QE128. (ii) Choose your default connection: Full Chip Simulation. (iii) Next > b. Project Parameters (i) Check the C language box. (ii) Project name: Type in a project name that makes sense to you. (iii) Location: Click the Set button and browse to a Location for the project. This should be on a drive or in a directory whereyou want to keep your HCS12 projects. (iv) Next > c.

In the Project Manager Window 4. Ensure Full Chip Simulation is to be used. If Full Chip Simulation is not shown, switch to the Simulator for debugging by clicking the pull down arrow and selecting it. (This does not use the hardware for debugging. If you want to actually use the MC9S08 hardware, choose P&E Multilink/Cyclone Pro orother hardware interface connection.)
