   2          实验接线：
   3          1、CPU板上的INT0接电机模块上的SIGNAL。
   4          2、试验箱（台）上的CS0832选择CS1，A/D模块上的DS的1、2脚短接，VOUT接电机模块的DRV。
   5          3、试验箱（台）上的CS244接CS0,244的输入IN0--IN7接平推开关KK1--KK8的输入K1--K8
   6          实验说明：
   7            全速运行程序后，在数码管的左两位显示设定的转速（16进制），此数值可通过与
   8          244输入端相连的8个平推开关kk1---kk8设定,同时在数码管的右两位显示电机实际转速，
   9          显示的格式同左两位。认真观察数码管的右两位数值的变化，可以了解电机转速的控制过程。
