怎么样才能转动步进机电机同时支持12864屏刷新，不会让电机转得太慢呢？

有人支招吗？》

fairsky 发表于 2014-1-9 10:47:39

发现电机转得特别慢如何解决呀？

zoologist 发表于 2014-1-9 11:32:30

你确定如果将下面的代码去掉之后电机转速会变快么？

do               //显示

   {
   u8g.setFont(u8g_font_5x7);//写文字
   u8g.drawStr(2,6,"Arduino Oscilloscope V0.1");
   u8g.setFont(u8g_font_5x7);//写文字
   u8g.drawStr(5,64,"Shenzhen R-tech Co.,Ltd.");
   u8g.setPrintPos(50, 50);

   {
    u8g.setFont(u8g_font_9x18);
    u8g.print(data);

   }   
   //u8g.drawLine(64,0,64,63);// 画坐标轴

      // u8g.drawLine(0,32,128,32);
   //for(x=0;x<128;x+=8)      //画坐标轴刻度
   //u8g.drawLine(x,31,x,33);
      // for(x=0;x<64;x+=8)
      // u8g.drawLine(63,x,65,x);

    }

能确定！我试过了

zoologist 发表于 2014-1-9 14:03:53

fairsky 发表于 2014-1-9 13:55 static/image/common/back.gif
能确定！我试过了

那我的建议就是继续在这段代码中一直删除东西试试

看看是因为某条语句耗时太长导致的。

当然有可能有2个结果：1.是某条语句导致的 2.放在一起整体导致的

先试试看吧

fairsky 发表于 2014-1-9 14:10:06

我现在希望能找到能够电机和显示同时执行互不干扰的方法就好了

fairsky 发表于 2014-1-9 14:11:20

因为我还有一个HX711称重传感器。执行一次要105ms{:soso_e101:}

zoologist 发表于 2014-1-9 14:15:14

要不你试试多线程库？我没用过，但是有可能解决你的问题

fairsky 发表于 2014-1-9 14:35:00

我试了那个PT库。我1.05版本表示执行不了~{:soso_e101:}

zoologist 发表于 2014-1-9 14:55:29

fairsky 发表于 2014-1-9 14:35 static/image/common/back.gif
我试了那个PT库。我1.05版本表示执行不了~

呃 我觉得那你的目标应该就是修改库，让他能在你的板子上运行啊～

这应该是最简单的方法了，特别是你还有一个耗时100多ms的传感器

rick_hou 发表于 2014-1-10 19:43:38

我是用定时器产生脉冲来控制步进电机驱动器，再由驱动器驱动步进电机的，屏幕当时用的IIC通讯的1602，没有发生什么延迟，至少感觉不到。所以不清楚对你有没有帮助

soinger 发表于 2014-1-11 10:52:50

用iic总线通讯连上几块板子，每块完成一个或者两个工作也行吧

friskit 发表于 2014-1-11 10:59:28

步进电机是需要独占定时器或者时钟频率的。。多轴步进电机联动一直是个科研难题，更别提步进电机+屏幕刷新了。。。。最简单的方法就是用总线连接两个小的arduino，一个用来控制步进电机，另一个用来绘图。再把这些连接到一个控制器（主机）上……然后让两个从机根据主机发送的数据各自运转

那三D打印机四轴是怎么弄的~~~
