Abstract

This paper describes the CAN bus, and gives the hardware interface circuit of CAN controller. Compared with the defects of principal and subordinate communication between microcontrollers, it raises peerto-peer communication between microcontrollers by the CAN controller. We also analyzed the principle of hardware and design of communication programs. The design take 82C200 produced by PHILIPS corporation as the chip of system. It sends and receives data by the module which consists of microcotroller, CAN controller and transceiver. Its software is made up of three modules for initialization, transmission and reception.
