单片机控制脉冲编码器实验，首先设定一个初值，脉冲编码器左转数值减少，右转数值增加，并通过1602液晶屏显示当前的数值。并带有软件防错功能，可以在一定范围内减小误动作。-SCM control pulse encoder test, first set up an initial value, pulse encoder values to reduce turn left, turn right values increased, and by 1602 LCD screen displays the current values. And with the software error prevention function, can be reduced within a certain range malfunction.
