How it works
The project consists of a state machine with 4 outputs, which is used to control a bipolar stepper motor.
How to test
The system has an external clock input, a reset input, a control input for selecting the direction of rotation of the motor, an enable input and 4 outputs for the stepper motor coils.
External hardware
The system requires an external clock input to control the speed of the pulses and thus regulate the rotation speed of the motor.
