LIN Sample Application for the MC68HC908EY16 Evaluation Board
To develop LIN applications in “C”, Metrowerk’s Codewarrior is an appropriate
development environment. To use Codewarrior with this simple hardware set-
up, use the following procedure:
10. Code should now run. If the source code has not been changed then the
11. To develop new LIN applications the source code file LEDemo.c should
1. Copy folder “Lin08EY” from CD to an appropriate place on local hard
2. Launch Codewarrior from Start menu: Programs - Metrowerks -
3. From folder “Lin08EY” drag file:

source file(s). This, and a procedure for creating a completely new
Codewarrior project, are described in detail in appendix I. Creation of a
new project allows development of a different application, with its own
LIN characteristics (message IDs etc.), without interfering with the
supplied demonstration application.
