| Abstract: | Combined with the feature of RS- 485, RS-232 and CANbus, the design of common serial interface to CANbus interface converter was described. On basis of the analysis of the technical performance and comparison of controllers, the main structure was decided and the hardware circuitry based on P87C591 was designed. By setting up working mode of the CPU built-in CAN-controller, controlling working state, and combining with software design, then data receiving and sending were realized, which meet the need of communication from common serial interface to CANbus interface. |
