Methods

/**
 * @fn DFRobot_Stepper
 * @brief Constructor for DFRobot_Stepper
 * @param totalSteps: the number of steps required for the stepper motor to make one complete revolution
 * @param INAPin: control pin for INA
 * @param INBPin: control pin for INB
 * @param INCPin: control pin for INC
 * @param INDPin: control pin for IND
 */
DFRobot_Stepper(int totalSteps, int INAPin, int INBPin, int INCPin, int INDPin);

/**
 * @fn setSpeed
 * @brief Set the rotation speed of the stepper motor
 * @param speed: sets the actual rotation speed of the stepper motor, in RPM (Revolutions Per Minute)
 */
void setSpeed(long speed);

/**
 * @fn step
 * @brief Set the number of steps for the stepper motor to rotate
 * @param stepNum: the number of steps the stepper motor will rotate, where the direction is determined by the sign of the number
 */
void step(int stepNum);
