步进电机控制器的设计
下面是我写的一个简单的程序，但是我不知道该怎么修改才能满足题目的要求以及转速和角位移的显示程序，麻烦各位帮我看看，说说你们的想法，现在这谢了啊

你现在能控制电机正反转动了吗?我也没有做过，一步一步的做吧，先让电机转起来，再来调速， 精度之类的功能
不知道你显示部分电路有了没有,是用液晶显示,还是用LED,请先说明一下,对应的外部电路有,才好对应进行编程...
你的程序还有很多没有完成。
单片机控制步进马达的方向，速度，位移的程序很简单。调速我还没有搞过。
用一个步进马达控制器就可以了。
用单片机设计一个步进电机控制器。要求能对步进电机实现正、反转及速度控制，同时能对步进电机进行位置控制，这个很简单。
这个问题是要能够设定步进电机的转速啊，通过键盘设定。你会编写这个程序吗?
下面是我的完整程序，就是我调节的转速好没有与实际的转速一一对应。你能帮我改写吗?
