Development And Application Based On Mixed-Signal SOC Platform

First this paper gives a brief introduction about the development progress of the embeded 8-bit microcontroller,which will still play an important role in the long future.we explain the new generation product of Silicon Labs--C8051F320/1,Silicon Labs designed a series of high-intergration microcontroller products for Vehicles Electric system,and we ,according to its application ,developed a platform based on the mixed-singal SOC -C8051F320/1,and made a test in the design of Vehicles network. In this thesis, the developing history, function and topological structure ofautomotive network control technology is comprehensively introduced. Theautomotive network standard emphasizing particularly on different functionssystematically is analyzed and the different main protocols is deeply discussed.After scanning and analyzing the developing trend of international automotivenetwork technology and considering its application and development status inChina, we have a conclusion that it is not benefit for the long-time developmentby purely importing technology. Quickly understanding and applying importedtechnology and developing automotive network standard of autonomousknowledge property right and exploiting automotive electronic product based onit is imperative under the situation.The subject is aimed at profoundly discussing the design scheme of fourdifferent classical automobile bodywork control network and providingcorresponding topological structure chart. The third scheme is selected throughanalyzing and comparing the four schemes. After simplifying it, the fourautomobile lights control system is substituted for CAN nodes directlyconnecting to CAN Bus network and then to central control node. Then the automobile light control network based on CAN Bus is realized.When this thesis is completed, the CAN communication in the experimentof automobile light control network platform has been realized. The resultindicates that the data can be transported at 125Kb/S baud rate stably, accuratelyand credibly. The basic thought of this design can be also used in otherdistributed CAN control system.
