Expand the groups in the CodeWarrior Projects view to display all the default files generated by the New Bareboard Project wizard.
The wizard generates following three C source code files, located in their respective folders in the project directory:
- main.c,
located in <project_directory>\ Sources
- Startcf.c, and
located in <project_directory>\ Project_Settings\Startup_Code
- mcf51ac128a.c
located in <project_directory>\ Lib
At this time, the project should be configured correctly and the source code free of syntactical errors. If the project has been built already, you should see a link to the project's binary files, and the FLASH folder in the CodeWarrior Projects view.
To understand what the IDE does while building a project, clean the project and re-build the project.
- Select
Project > Clean
from the IDE menu bar.
The Clean dialog box appears.
- Select the Clean projects selected below option and select the project you want to re-build.
- Clear the
Start a build immediately
checkbox. Click
OK
.
The Binaries link disappears, and the FLASH folder is deleted.
- Select
Project > Build Project
from the IDE menu bar.
The Console view displays the statements that direct the build tools to compile and link the project. The Binaries link appears, and so does the FLASH folder.
During a project build, the C source code is compiled, the object files are linked together, and the CPU derivative's ROM and RAM area are allocated by the linker according to the settings in the linker command file. When the build is complete, the FLASH folder contains the CF_project.elf file.
The Linker Map file ( CF_project.elf.xMAP) file indicates the memory areas allocated for the program and contains other useful information.
To examine the source file, main.c, double click on the main.c file in the Sources group. The default main.c file opens in the editor area. Refer the following figure.
Use the integrated editor to write your C source files ( *.c and *.h) and add them to your project. During development, you can test your source code by building and simulating/debugging your application.
