You could repeatedly call move(), but after a while, the 32-bit integer that stores the target position will overflow, causing the motor to reverse its rotation. } Why use this library instead of AccelStepperĪccelStepper is an excellent library when you want to move a stepper motor shaft at a specific angle (for example, in a 3D printer), but it doesn't support applications that need continuous rotations.ĪccelStepper provides a runSpeed() function for continuous motion, but it doesn't accelerate smoothly. Set the four pins to LOW, hereby stopping all current in the coils. Restore current in the coils and restores the current speed. void begin( uint8_t pin1, uint8_t pin2, uint8_t pin3, uint8_t pin4) Configures the stepper with the specified pins. Sets the enable pin's level to its inactive level. Sets the enable pin's level to its active level and restores the current speed. void setEnablePin( uint8_t pin, bool activeLevel = HIGH) The pin is set to its active level unless powerOff() was called. You can pass LOW as the second argument to invert the logic. void begin( uint8_t stepPin, uint8_t dirPin) In addition, ContinuousStepper inherits some functions the TStepper class: Tells whether the shaft is currently spinning. void setAcceleration( float_t acceleration) During accelerations and decelerations, this value differs from the // target speed configured with spin(). Call isSpinning() to know when the motion is complete. The shaft will smoothly accelerate or decelerate to reach the // target speed. See StepperDriver and FourWireStepper below for details. Turn the power on and restores the current speed. You must call this function as frequently as possible. Updates the status of the step and dir pins. Public: // Initialize the class and attaches to the specified pins. How to use the ContinousStepper library? Basic example with a stepper driver Uses neither delay() nor delayMicroseconds().Optionally uses Khoi Hoang's PWM libraries (RP2040_PWM, SAMD_PWM, AVR_PWM, STM32_PWM, Teensy_PWM.).Optionally uses PWM with analogWriteFrequency() on Teensy 3 and 4.Optionally uses tone() instead of digitalWrite() for the step pin.Optionally runs with TimerOne, TimerThree or TeensyTimerTool.stepper drivers with step and dir pins (and optionally enable pin).It smoothly accelerates and decelerates when the speed changes. Instead, it provides one function to spin the shaft at a specific speed. An Arduino library to spin stepper motors in continuous motions.Ĭontrary to other stepper libraries, this one doesn't provide any function to move the shaft at a specific angle.
