| 楼主牛人，学习了！ |
mqwu 发表于 2014-10-1 11:12 请教下，如何控制直流马达停止及圈数？ |
| 非常好东西，学习一下！ |
| 没有影响，因为PIC18系列运行一个指令周期很短，只要4个时钟周期，你若用4M的晶振， 也就需要1uS,而数码管的动态扫描用的delay(10),就相当于10x10uS,远比E2PROM写和读长。 |
|
当运行EEPROM_write();时， 对数码管显示，步进电机有影响吗 |
| 其实理工男蛮苦的，整天面对电子元件和电脑，较尽脑汁做一些屌丝们都不愿意做的事，也没有楼上你说的那么有才， 只是忘掉世俗的浮躁和唯物拜金，做一点自己喜欢的事情罢了。同时也为了能够生存混口饭吃，就这么简单。 |
| 是的，你说的非常正确 |
| 底下那个传感器是用来检测标签到位吗 |
mqwu 发表于 2014-10-1 11:12 兄弟你太有才了，不得不佩服，这样具有学习能力的单片机大有前途呀。 |
| 用来贴产品的标签，每次员工值接用一只手就可以贴标签了， 没有这个势必要用两只手，相当于解放一只手拿产品做别的事，效率提高了，下一步，我打算用直流带减速器马达， 用PWM+AD来改变占空比控制，这样电路更简洁，程序更优化，我查了下，淘宝上卖的都是这种设计，我准备做个5台给生产线试用 |

本帖最后由 明白 于 2014-10-1 11:13 编辑 步进电机速度高了，噪音挺大 机器用来干什么的？ 先占个位！  请楼主讲解一下是干吗的！ |
|
非常有水平，做得挺牛 建议楼上跟中央台《我爱发明》栏目联系，会优先采纳。 |

| 好东西 ，楼主能上传个电路图吗？ |
| 佩服啊 换个壳子的话 就可以量产做产品了 应该有销路的. |
| 大神级别的作品啊 学习了 |
