The LIN protocol was originally designed by a group of
European carmakers to be used as a low-cost, short dis-
tance, low-speed network for automotive applications
(see Appendix C: “References”).
The main characteristics of the LIN protocol are:
• Serial communication
• Single master, multiple slave concept
• Low-cost, one-wire implementation
• Speed up to 20 Kbit/s
• Self-synchronization (on the slave side)
• Ensured latency time in transmission
This application note presents a Microchip Application
Maestro™ compatible interrupt driven implementation
of the Master Side Driver of the LIN protocol in a
PIC18F device in C language (Microchip and HI-TECH
‘C’ compatible), which takes advantage of the new
features provided by the PIC18 Enhanced USART
module. AN891
