In actual LIN applications a signal-based messaging scheme should be
adopted. Refer to section
details of Motorola’s signal-based LIN API.
The demo consists of 13 LIN nodes; a single master and 12 slaves. The
hardware for each node is identical as shown in the schematic (see
appendix for schematic details). Identical hardware was used to enable
a universal master/slave board to be designed. This makes the slaves
more flexible and reduces demo cost. The main drawback of adopting
this common solution is that the microcontroller required for the master
node, MC68HC908AZ60, is not suitable for slave nodes because of its
additional functionality (particularly CAN). This makes it too expensive
for a typical slave node.
