一个分别控制继电器的程序,有段是飞轮正转几圈然后就反转几圈的程序.-A control relay, respectively, the procedures have paragraphs are flywheel is then transferred laps laps on the inversion procedure.

设有n各人坐在一圈，并按顺时钟方向从1到n编号，从第s个人开始进行1到m的报数，报到第m个人，此人出圈，再从他的下一个人重新开始从1到m的报数，如此进行下去直到所有的人出去为止。要求按出圈次序每十人为一组，给出这十人的次序表。-Sitting in a circle with each n, and clockwise from 1 to n number of individuals from the first s start from 1 to m of the reported numb

single-chip stepper motor control, subdivision 2, a step of 0.9 degrees, walk around 400 pulses required radius 33mm, around 20 laps to go away need 0.10362m 8000 pulses. Accelerated to 4000, the slowdown of 4000, when Timer 0 period of 60ms to 40ms

利用PWM的方式来控制两相四线步进电机的转动、正反转、转速、在什么位置停、在多少圈后正转或者反转-Use PWM way to control two-phase four-wire stepper motor rotation, rotating, speed, stop at what position, how many laps after the forward or reverse
