BASIC Stamp 1 Application
This program demonstrates basic full-step, high-torque control of a unipolar stepper motor.
sequence data is stored in an EEPROM table to simplify program design and modification. Separate
subroutines are used to manipulate the step index pointer that controls rotational direction. Note that
the stepper update routine (
used by the stepper motor.
