| Abstract: | A design solution of CAN smart node based on AT91RM9200 and MCP2510 is put forward. Firstly, the design principle of hardware for CAN smart node is depicted, and the type of selected chips is also presented. Then, the design flow of software for CAN smart node is depicted in detail. Finally, the debug method of hardware and software for CAN smart node is illustrated. Both the design and debug work of hardware and software for CAN smart node were finished, and it was migrated to run in VxWorks5.5 operating system successfully. The design solution is proved to be proper and feasible. |
