API

stepmotor = Stepmotor('Full')

• Initializes the stepper motor, setting the stepping mode to full step, which affects the motor’s stepping style and precision.

stepmotor.disable()

• Disables the stepper motor, stopping its operation so it will no longer receive movement commands.

stepmotor.enable()

• Enables the stepper motor, allowing it to begin executing commands and responding to control signals.

stepmotor.get_status()

• Gets the status of the stepper motor, typically used to check whether the motor is enabled or operating normally.

stepmotor.get_voltage()

• Retrieves the voltage of the stepper motor, potentially for monitoring power supply conditions to ensure the motor operates within the correct voltage range.

stepmotor.move_circles(0, 0)

• Sets the motor to rotate a specified number of circles in a clockwise direction, used to control the motor's rotation angle.

stepmotor.move_steps(0, 0)

• Sets the motor to move a specified number of steps in a clockwise direction, allowing precise control over the motor’s rotation angle.

stepmotor.reset()

• Resets the stepper motor or a connected device to its initial state.
