4 EXAMPLES

The purpose of this chapter is to give you an example, describing step by step how to use the

LIN software. This example was defined to demonstrate the LIN software and not to show a

typical LIN application.

The network consists of the master node and 2 slave nodes.

The application example is slave1.

The LIN communication consists of 4 LIN frames.

(*): The example is given for the LIN specification package 1.1 as many tools still don’t support
