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.
