这算法太烧脑，弄完了，头晕眼花的

算法还是不太行，显示的速度和效果和原来的驱动差距不小

三、总结

终于有进展了，算法可能不是最优，但实现了。

移动速度慢主要的原因是595是外部设备，对它的操作会远远慢于51内部的计算耗时。尝试过优化除法、乘法、取余这些运算，但提高效果有效。

最有效的提高移动速度的方法是：

1、烧录时，使能6T，可以提高一倍速度；

2、for(n=0;n<1;n++)，那句可以改成for(n=0;n<16;n+=2)，显示可以清楚一些，步子大了，显示速度也快了，并且人眼几乎看不出和一步一步走的差别。

这个算法数据本身没有动，通过取值来控制输出。但就像牛屎芯片一样，自己都看不懂到底是个啥。
