Each MPC5200_Quick_Start project contains a single source file named “main.c”. This file contains typical “Hello World”
application source code.
If a user application grows beyond the single source file (which is most likely to happen with MPC5200 applications), it is the
user’s responsibility to add other source files to the CodeWarrior project.

This section describes the Graphical Configuration Tool which is included in the MPC5200_Quick_Start development
environment. The Graphical Configuration Tool (GCT) is a standard Microsoft Windows-based application used to graphically
edit (read and write) project’s “appconfig.h” file. All control bits and bit-fields of each MPC5200 peripheral module are presented
in an easy-to-understand graphical form. The register initialization values edited by graphical controls can be immediately
displayed and/or written back to the “appconfig.h” file. Here they are used by the module initialization code to set up the individual
peripheral modules. As it was already described in
peripheral modules which are to be automatically configured before entering the application’s main() function.
6.1
The most effective use of the GCT is to integrate it into the CodeWarrior development environment and assign a hot-key or menu-
item for invoking it. In such a configuration, the GCT is automatically opened for the project currently active in the CodeWarrior
IDE.
A detailed description of how to integrate the GCT into CodeWarrior IDE can be found in the “todo_CW.txt” document in the
MPC5200_Quick_Start installation. The procedure is also briefly described below.
In the CodeWarrior, select the menu “Edit / Commands and Key Bindings”. In the “Customize IDE...” window
the menu group in which you want to create a new “GCT” menu item (e.g. “Project”).
