controlling stepper motor by 8051

[anasfuad33eng]

hi, all
i want to program 8051 mcu to receive 5 digital input for example if the digital value 0 the stepper motor not rotate
else if digital value 1 the stepper motor rotate cw direction 72 degree then stop
if the digital value 2 will rotate another 72 degree cw direction then stop
if the digital value back to 1 stepper motor rotate 72 degree in ccw direction then stop and so on
please help with codes in assembly language
thanks in advance

hai,
how u are giving the digital data to muc? is it through serial communication ?

by using potentiometer and adc but the idea how i can make stepper motor rotate 72 deg if the digital value=1 then the motor stop to check the next
digital input if the digital input=2 the motor rotate another 72 degree,please help8-O
