| Abstract: | This paper presents a kind of design scheme for dis-tributed measure and control system based on CAN bus withCAN I/O expander MCP25050. A hardware design for mainnode and the CAN bus interface are proposed, and the overallarchitecture, hardware configuration, software functions are dis-cussed in detail. It is indicated through experiment that the sys-tem is simple, reliable and cheap for CAN bus application. |
