用定时器实现步进电机控制方案。

步进电机要做好真正加速、高速、减速的控制过程，还是不容易的。

上述方案进行简单更改，就可以与步进电机驱动器一起实现，步进电机的加速、减速、高速过程。运行频率10K以上，在我们的控制器里已经成功运行。同时，在我的水晶球数控系统中，运用良好。

ljhlxq 发表于 2010-9-12 11:12:05

还得说上一句，以上应用，参考了九九的定时器应用笔记，表示感谢，对于九九本人，若有需要和项目合作，可以与本人联系。

youxin2004 发表于 2010-9-12 13:35:17

请问楼主运行在10k以上是什么意思？用的多少细分来带步进电机？

ljhlxq 发表于 2010-9-12 14:08:43

运行10K，细分为4，步距脚1.8。这个是与步进电机和驱动器有关的。大概1000转每分钟；实际运行700转每分钟，带负载。

定时器停中断有点太占用资源了

ljhlxq 发表于 2010-9-12 15:33:12

12楼的想法在我设计之初，也是这样认为。可以用DMA的方式，关键看你的系统怎么设计

slj0620 发表于 2010-9-12 15:50:16

我就用TIM和DMA设计的一片带两个电机口，实际可支持到100K以上（程序速度优化），只在加速到恒速，恒速到减速，加速到减速切换过程中断

ljhlxq 发表于 2010-9-12 16:04:00

14楼是高手，有幸认识。希望有很好的想法，并且实现了的话，可以拿出来共勉。

ljhlxq 发表于 2010-9-13 10:36:40

对于文本显示器+PLC的方案；工业触摸屏+PLC的方案；在工业上已经非常成熟了，呵呵，最近做个项目，替代那个PLC.
由于PLC的价格相对而言，肯定比较高，用STM32替代PLC，那么与文本显示器、工业触摸屏就有个通信协议的问题，大家不知道有没有相关经验，一般而言，与文本、触摸屏就是RS232或RS485通信，目前我就用STM32替代了台达(DVP)的PLC，关键是MODBUS-RTU协议的实现，呵呵，可能还有些问题，所以，大家有没好的点子、经验，来晒晒。
我这个主题发到了AVR32中去了，请大家在这也进行一下讨论？？？？？？？？？？？？？？？？？？？？？？？

到网上搜索下激光雕刻机光驱；你会的到文章里面使用avr 8位实现运动控制功能并能进行G代码解析参考下那个代码吧灰常不错我想应该可以转到stm上的 8位实现了直线运动梯形加减速直线插补圆弧插补。。。。。16M晶振步进频率可以到30k。内部使用命令缓冲序列形式缓存20个命令序列；如果做舞台灯用只用把运动序列改为死的或者放到eep中进行合理加载进行类似循环播放的形式应该灰常不错，估计控制舞台灯轻松。

我就用TIM和DMA设计的一片带两个电机口，实际可支持到100K以上（程序速度优化）主要部分程序
void DMA_Conf ...

请问19楼中的const unsigned shortMotorCurve8这个大数据表格是怎么计算出来的？知道的科谱一下计算方法啊。
