I find this is helps to avoid skipping steps when starting and stopping movements. The particular advantage of this library is that it handles accelerations (i.e. This makes me think this must be related to the priorities of the interruptions. An interrupt-driven stepper motor driver for Arduino. You should post a timing-diagram that clearly shows the relations between the step-signal for the stepper-motor and the laser-trigger-signal. 0 How to Generate PWM for control servo motor on STM32F103 with Timer. Motor 1 is related to timer 3 and motor 2 to timer 4. You need a non blocking stepper library like my MobaTools or Accelstepper. I wanted to move my BLDC motor using a timer interrupt. Although, if its motor 1 who has to do 34 steps and motor 2, 18, everything works. In this case, both motors 1 and 3 finish but motor 2 gets stuck and does not move any more. Examples Motor knob: Control a highly accurate stepper motor using a potentiometer. To use this library: include Circuits Unipolar steppers.Now permitting using servos with different pulse ranges simultaneously. To use it you will need a stepper motor, and the appropriate hardware to control it. This library enables you to use 1 Hardware Timer on RP2040-based board, such as NanoRP2040Connect, RASPBERRYPIPICO, to control up to 16 or more servo motors. This only happens under one condition: when motor 1 has to do 18 steps and motor 2, 34. 1.0.1 1.0.0 Usage This library allows you to control unipolar or bipolar stepper motors. My problem is that, at some point, my interruptions crash and one of the motors stops working. This way, at each interruption, I make the motors do one step and, after that, I set the new compare value for the timer in order to reach the new velocity to move at. For so, I use timers 3, 4 and 5 in compare mode. In order to do so, from the distances to move of each of the motors, I calculate the amount of steps to do and the velocities for each of those steps in order to ensure that all the motors finish at the same time. TB6600 Stepper Motor Driver with Arduino Tutorial. The goal is to move to different positions applying accelerations and decelerations while finishing all of them at the same time. There is no direct need for interrupt handling to commutate the motor timer. I am working with a MEGA2560 trying to implement velocity ramps for three steppers at the same time.
