做毕业设计要用到57步进电机，所以花了两天时间做了一下电机函数
从淘宝查的资料：
接线如图：
DIR- && PUL- 接 单片机GND
DIR+ 接 PA1
PUL+ 接 PA0
驱动盒TB6600 VCC 24V
驱动盒TB6600 GND 24V的GND
我测出来的 A组（绿+蓝- ） B组（黄+红-）
如何确定AB两组看这个：

先冲英说明：
Microstep Driver 微步驱动程序
Microstep 微步
Pulse 脉冲
我开关SW设置成这个样：
1 off
2 off
3 on
4 on
5 on
6 off
对应下图：
代码我参考我之前用arduino写的驱动程序

理论上角度是可控的了，
3200个脉冲为一个周期，映射成360度
1600个脉冲，为180度
800个脉冲，为90度
400个脉冲，为45度
45°x=400
x约等于9（8.888888888888889）
得出角度系数约等于9
945=405
9*8.888888888889=400.000000000005
（小偏差，我能接受，但是做项目不行，你们有更好的算角度的，可以留言说一下）
