Description:
|
The LIN protocol was originally designed by a group of European carmakers to be
used as a low-cost, short distance, 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.
