7-4、S加减速转动实现【51单片机控制步进电机-TB6600系列】

摘要：本节介绍实现步进电机S曲线运动的代码

一、目标功能
实现步进电机转动总角度720°，其中加减速各90°
加速段：加速类型：S曲线
　　加速角度：角度为90°
　　起步速度：30RPM，
　　终止速度：500RPM
匀速段：匀速角度：角度为540°
　　匀速速度：500RPM
减速段：减速类型：S曲线
　　减速角度：角度为90°
　　起步速度：500RPM
　　终止速度：60RPM
在这里插入图片描述
二、生成器计算
加速参数计算

匀速参数计算，主要计算电机步数

减速参数计算

三、程序代码

//加速、匀速、减速步数
#define step0 100
#define step1 600
#define step2 100unsigned int n=0;//步数计数变量
unsigned int flag=0;//标志位，0：加速段  1：匀速段   2：减速段//加速段90°，30RPM-500RPM
