motor direction controlled by Dial control

[ydeng]

how to control the direction of motor by using Dial control,for example, if the pointer locates the negative area, the motor would reverse.  Generally the direction of motor is determined by the values of AIN2 and AIN1 in micro chip, if the value of AIN1 is bigger than that of AIN2, the motor would turn in certain direction, if not, the motor would reverse. However, I want to use only Dial control to control the direction. What should I do?
