Hi glee_glare,
You are right and actually this is why we come out with these stepper motor drivers. Generate step sequence is a resource consuming process when your controller is not only taking care of the stepper motor alone. Proper algorithm is needed to achieve that.
With these drivers, you only need 3 pins to control the stepper motor driver which will help you to generate the correct step sequence. Your controller only needs to give pulses and control the enable and direction signals. Each single pulse to the stepper motor driver will trigger the stepper motor to move one step at the given direction. The frequency of the pulses you give will determine the rotation speed of the stepper motor.
I hope I clarified your doubt.
