In the application of controlled systems, Fieldbus has improved the development of the comprehensive controlled technique,which has been a hot topic in the field of control .Controller Area Network belongs to the category of the Fieldbus.Due to its transcendent characters,the fantastic reliability and the special design,CAN has reached the international standard and been applied more and more popular in the aspects of interconnectiong of the industry automation device.Moreover,it’s regarded as one of the most promising Fieldbus by the public.
This article introduced the design program of CAN correspondence in the Intelligent House.At the same time,this paper declared the design thought of this program carefully with its function and characters.The design of this article focused on the Intelligent House as the applied goal,then fulfilling the correspondence of Intelligent House by the CAN fieldbus.So that the controller without CAN function at the begine can fulfill the correspondence of the CAN Fieldbus rapidly.The specific design regarded the ARN chip S3C2410 as the core of the whole design.Because S3C2410 had not CAN controller,so I choosed MCP2510 as CAN controller and the SPI interface as channel.The software of this design was mainly about modular design .In order to clera the task of each module,I devided the undeveloped software system into several separate module.The hardware of this design was designed in terms of the tipical CAN design and the parameters of each chip pin strictly.
We can see from the result of this experiment ,the design can fulfill the correspondence function of CAN so that the data can be sended and received by itself.
