stepper motor

[pratti]

can anyone help me with the code in8051 microcontroller to rotate stepper motor in clockwise and anticlockwise direction.on what factor does the delay tine and angle is determined?
for eg,
po=0xaa;//this aa or whatever the value is but how can we decide this?
delay(75);/how to determine the delay time
plz help me

delay time that u write is basically the multiple of 1275 microseconds cuz of crystal oscillator. so use accordingly.. whateva de value u write fr delay under brackets if u want delay in seconds.
e.g., delay(100) wud b equal to around 1 second delay

and aa value that u write is hexadecimal..
