The Communication Research Of Embed ARM9200 And MCP2510

With the applying of the embed abroadly,the applying of the embed periphery interface is becoming more and more important.Mostly applying on PDA,the moving computer equipment,the top box of TV,mobile telephone internet,numeral TV,multimedia,motorcar,the stove of microwave,numeral camera,the system of familuy automatization.,moving staircase,air-condictioning,the safety system,automat,the telephone of honeycomb,the consumption of electronical equipment,the instrument of industry automatization,and the instrument of medical treatment.This text the instroduces configuration and function of AT91ARM9200 of Ttmel corporation and MCP2510 CMOS chip of America microchip science and technology corporation,introduce importantly the SPI interface connect of and MCP2510 CMOS chip, expound the communication process of MCP2510 and linux programme.This paper aims at mostly the communication of embed AT91ARM9200,as follows: the recommendation of configuration and function AT91ARM9200 and MCP2510, importantly introduce the communication process of MCP2510 and AT91ARM9200.This paper makes use of the SPI interface of AT91ARM9200 to connect CAN communication module MCP2510,and design hardware principle map of AT91ARM9200 of Ttmel corporation and MCP2510 CMOS chip of America microchip science and technology corporation,and then make use of linux kernel to compile the testing program.On the collection module, separately design hardware principle map of weight collection module of chain block and displacement collection module, the singlechip adopt PLC938 chip,make use of assemble language to program PLC938 chip, connect the MCP2510interface of AT91ARM9200 and MCP2510,startup linux kernel,run the testing program,make use of computer to connect serial interface of AT91ARM9200, examine the result, analyze the testing result,and remend the program.By testing,the sending data of AT91ARM9200 and MCP2510 both receive,also see it,improve the design of hardware and software accord with the request of design.Finally, summarize the work of paper, point out the direction of the future research.
