stepper motor interfacing

[Radha.P]

Hai,

     I connected stepper motor to P1.0  to P1.3 and switch to P1.4 of 89s52  .First check the SW when this switch value is low it should rotate in  anticlock wise direction (ROTATE MOTOR IN ANTI CLOCKWISE DIRECTION TILL SW O/P IS 1(APPROXIMATELY 20 STEPS)),and if  IF SW==1   ROTATE MOTOR  IN CLOCK WISE TILL SW==0 OR 1100 steps. If SW==0 rotate motor 20 steps clock wise and, and again rotate motor in anticlock wise till SW==1.Plz send the code, i have written code but it is not reading switch value.
