伪随机序列编码源程序-an encode program of pseudo-random sequence

应用背景基于STM8S库函数的工程模板，基于企业实际工程使用，绝无delay等不切实际的，误人子弟的做法。以流水灯为例，简明扼要地演示了该程序。关键技术基于IAR for STM8的工程模板，无delay延时这样的不切实际的做法。位域时间平台标志位，TIM1定时器中断计时，基于库函数编程。

通过提升机械传动轴的转角脉冲计数,将计数值与预置值作对比,即可确定驱动电机的启停升降,达到平层就位的目的.以AT89C51为CPU,在中断处理程序中对外来脉冲计数.-Through enhancing the mechanical shaft angle of the pulse count, will be of value for comparison with preset values, you can determine the start and stop the motor-driven movements, to achieve the purpose of flat layers in place. To AT89C51 for the CPU, interrupt handling procedures in foreign pulse counting.
