| 摘 要： | 在电动机车的工程背景中，为了简化主控芯片TMS320LF2407A硬件上的外围电路以及软件上的程序编写，就把一些实时性要求较低的任务交给MCS_51去完成。主从芯片之间正确的数据传输是整个系统良好工作的保证。介绍了数字信号处理器TMS320LF2407A与单片机MCS-51之间基于RS_485的串行通讯设计方法，实验结果表明了这种通讯设计方法的准确性。

| Abstract: | In order to simplify the periphery circuit and the program of TMS320LF2407A, some complicated tasks are given to MCS_51. The right communication is a guarantee of the system. A design of semi-duplex serial-communication between a digital signal processor TMS320LF2407 and single-chip microprocessor MCS_51, which is based on MAX485, is presented. The experimental results show the feasibility of this method. |
