1、基于单片机的步进电机控制(软件)摘要步进电机由于用其组成的开环系统既简单、廉价，又非常可行，因此在打印机等办公自动化设备以及各种控制装置等众多领域有着极其广泛的应用。本文介绍的是一种基于单片机的步进电机的系统设计，用汇编语言编写出电机的正转、反转、加速、减速、停止程序，通过单片机、电机的驱动芯片ULN2004以及相应的按键实现以上功能，并且步进电机的工作状态要用相应的发光二极管现实出来。本文内容介绍了步进电机以及单片机原理、该系统的硬件电路、程序组成，同时对软、硬件进行了调试，同时介绍了调试过程中出现的问题以及解决问题方法。该设计具有思路明确、可靠性高、稳定性强等特点，通过调试实现了上述功
