[Abstract]:In this paper, the embedded system application technology and can bus application are effectively combined, and the hardware, protocol and driver of can bus are analyzed in detail, and SPI bus is analyzed at the same time. On this basis, the can bus is applied and programmed. By extending the can bus on ARM9 and setting up the can bus network, the communication between several ARM9 through can bus is realized, and a correct test and a successful application example are given. In this paper, UP-TECH S3C2410 / P270DVP embedded development platform is used as the hardware platform, and embedded Linux operating system is used as the software platform to program the can bus to initialize the hardware, send and receive the data and so on. The thesis is divided into five chapters: the first chapter introduces the research background. The present situation and development trend of embedded system and can bus are introduced in detail. The second chapter introduces the hardware and software platform and the construction of the development environment. It includes the introduction of experimental platform, the establishment of cross-compiling environment, the construction of PC Linux system environment and programming environment, the boot program, the transplantation of kernel and root file system, and so on. In the third chapter, can bus is analyzed in detail. It mainly includes SPI bus analysis and can bus hardware analysis, protocol analysis and driver analysis. The fourth chapter carries on the application programming to the can bus. The implementation and test of the program are emphatically introduced, and a successful application example is given. The fifth chapter summarizes the full text, and points out the future work and research direction.
