摘　　要：针对目前复杂多处理器通信的需要,介绍了一种数字信号处理器TMS320LF2407A与单片机MCS-51之间基于CAN总线的全双工串行通信的设计方法。方法将整个控制器系统构成通信网络,具有分布控制,实时传输数据以及良好的可拓展性。应用于电动汽车核心控制器系统中,测试结果表明,基于CAN的串口通信设计能够准确、快速地传递数据信息。In light to the need of complex multi-processors communication,a design approach for CAN bus-based full-duplex serial communication between a digital signal processor （ DSP） TMS320LF2407A and a single-chip microprocessor MCS_51 is presented. The whole control system is constructed to a communication network by this method with distributed control,real-time data transmission and good scalability. It is applied to electrical vehicles’core controller system. Test results show that the CAN-based serial communication design can transmit data information correctly and quickly.
