摘　　要：本文介绍了以TMS320LF2407A为核心控制器的步进电机自动升降速控制系统与PC机的通讯及程序设计方法。文章分析了通讯协议及数据传输的格式,详细介绍了DSP和上位PC机的软件设计,给出了程序的流程图和人机控制界面,并在步进电机和步进式伺服电机上,进行了相关的实验,基本上达到了控制的要求。It's introduced that the controlling system in raising and reducing speed of stepper motor that is based on core controller, TMS320LF2407A, communicates with PC, as well as the method of programming. Communication protocol and data conveying format are considered in this article, which give the designing of software of DSP and PC, also give the flow chart of the involved program, the interface of man-machine controlling. Test has been done on stepper motor and stepping actuating motor, and the requirement is achieved basically. It shows the scheme feasible.
