| Abstract: | The basic principles on read /write data in the mode of Enhanced Parallel Port, CAN Bus and a Stand-alone CAN controller(SJA1000) are introduced. The architecture figure of the hardware design of the connection between the parallel port and SJA1000 for communications is presented. Also the software design principles are described in detail. The communication mode can be widely applied in power plant, substation and distribution automation system which has the properties of high communication speed, long distance, good flexibility, strong error detecting ability and low error code rate. |
