【Abstract】 LIN-Bus is a kind of low cost field bus. It is used in some situation where the request for communication speed is not so strict, and it also can be used as the subBus of CAN Bus. The characteristic of LIN Bus is introduced. The protocols of physical layer and data link layer are analyzed. The difference between LIN Bus and RS485 Bus’s merit and demerit are compared.更多还原
