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
You have concluded 70/60 Rrevolutions/second. You have concluded 200 steps in a revolution. Obviously, you need 200*7/6 steps / second. If you have read the datasheet, you know if there is one, two or more clock pulses for each step of the motor. The documentation for your processor will then inform how you configure it to generate such a frequency.
