Like most network protocols, the Local Interconnect
Network (LIN) as described in the official specification
is a multi-layered system. The levels vary from the
physical interface up to the high level application, with
logical data connections between nodes at various lay-
ers. This application note focuses on the implementa-
tion of an interface between the physical interface and
higher level application firmware, essentially a hard-
ware driver (the shaded blocks in Figure 1). Specifi-
cally, this document presents a Master node driver that
is designed for PIC18 microcontrollers with a standard
USART module. AN235
