| Abstract: | In this paper, we present a distributed control programs that based on TMS320LF2407 DSP chip, Controller Area Network and the protocol conversion modules between serial RS-232 and CAN network;Implementation of the serial RS-232 and CAN bus communication of data between, thereby achieving the communications between PC and the nodes under the CAN bus, achieving a distributed control functions. This paper introduces the Controller Area Network structure and working principle and hardware and software design. Practice has proved:The network can be used as is the RS232 network upgrade networks, also can be used alone, its circuit is simple and set up flexible, fast and reliable performance and has good adaptability. |
