stepper motor

i m interfacing the stepper motor with 8051 i hav all circuitry ready but i want to know how to generate the required RPM for stepper motor
EG: i want to run my motor at 60 RPM then what all calculations are required i hav taken a timer for the clock pulses but confused in the calculations
do u hav any sample program for it
i m using ic which has clocks pulse pin, i will be giving the clocks to that pin

  • If you have an IC that only requires a direction and a clock signal, then everything is easy: Just experiment!

    The datasheet for the IC will tell you how many clock pulses it needs for one step of the stepper motor.

    The datasheet for the motor will tell how many steps in one revolution.

    Now, you should have a quite good idea about how many pulses you must generate each second...

    A different issue is to figure out how fast the motor can accelerate, and if it is important that it never looses a step during the acceleration phase.
