| Abstract: | This paper introduces the way of designing communication node based on CAN bus. After introducing the main technical characteristic of CAN bus and its position in the industrial control system, it gives components for designing communication node of CAN bus and its characteristic of hardware and it also gives the designing chart of hardware of communication node. The design of hardware and software is described in this paper,it also gives the initialization process of CAN controller and the flow chart of sending and receiving data program. The method of design in this paper is easy to grasp and is flexibility and versatility,it can be used to control in many industry fields. |
