What is CAN (Controller Area Network)
•Proposed by Bosch with automotive applications in mind(and promoted by CIA -of Germany -for industrial applications)
•Relatively complex coding of the messages
•Relatively accurate and (usually) fixed timing
•All modules participate in every communication
•Content-oriented (message) addressing schemeFilterFilterFrame
CAN objective is to achieve reliable communications in relatively critical control system applications e.g. engine management or anti-lock brakes. There are several aspects to reliability - availability of the bus when important data needs to be sent, the possibility of bits in a message being corrupted by noise etc., and electrical/mechanical failure modes in the wiring.
CAN Bus Advantages
•Accepted standard for Automotive and industrial applications–interfacing between various vendors easier to implement
•Freedom to select suitable hardware–differential or 1 wire bus
•Secure communications, high Level of error detection–15 bit CRC messages (Cyclic Redundancy Check)–Reporting / logging–Faulty devices can disconnect themselves–Low latency time–Configuration flexibility
•High degree of EMC immunity (when using Si-On-Insulator technology)
it is so nicely explain...i think the best way to discuss on any topic is like the same
bz when u didnt aware of the topic and dont want to waste ur time in reading a lot and after u feel that its not for me so as per me the best way to discuss
