8051 connection to stepper motor by ULN2003 driver, help!!

halo, guy

i am using 8051 microcontroller to control unipolar stepper motor.
and i am confuse with sequncing for manipulation stepper motor.

anybody can help code a program using assembly language interfacing 8051 to identify how many step need to load in stepper motor from signal 8051.

ur help will be very appreciated!

    The sequences is rolling each step.
    Eg:
    1st= 0 0 0 1
    add here some delay
    2nd= 0 0 1 0
    add here some delay again
    3rd= 0 1 0 0
    add delay
    4th= 1 0 0 0
    add delay
    ---------------------------one roll, some 5 degrees per step
    back again to 1st

    You may modif anyway you want.
