Case study implementation and example of CAN BUS
Aim: Case study, implementation and example of CAN BUS 1. What is CAN? CAN,which stands for Controller Area Network, is the serial communication protocol internationally standardized by ISO *1. The automobile industry has hitherto witnessed the advent of various electronic control systems that have been developed in pursuit of safety, comfort, pollution prevention, and low cost. These control systems, however, presented a drawback in that since the communication data types, required reliability, etc. Differed between each system, they were configured in multiple bus lines, resulting in increased wire harnesses. Therefore, the need arose for reducing the number of wire harnesses, transferring large amounts of data at high speed via multiple LANs, and so on. To meet the need, BOSCH, an electrical equipment manufacturer in Germany, developed CAN in 1986 as a communication protocol for automotives. Thereafter, CAN was standardized in ISO 11898 and ISO 11519, establishing itself as the...
