It means it that it actually has 32 x 64 2048 steps. In addition, the motor has a 1/64 reduction gear set. That means there are 32 steps per revolution (360°/11.25° 32). It’s an I2C controller allowing several shields to be used. According to the data sheet, when the 28BYJ-48 motor runs in full-step mode, each step corresponds to a rotation of 11.25°. I have included a wiring diagram, a tutorial on how to set the current limit and many example codes. Something like “Digilent chipKIT Motor Shield. This article includes everything you need to know about controlling a stepper motor with the A4988 stepper motor driver and Arduino. If you can use extra hardware, and offload the “move-n-steps” logic: I looked at AccelStepper, which appears to do smooth motion by sending pulses at the right time in loop(). The motor is attached to digital pins 8 - 11 of the Arduino. What are the Arduino IDE libraries that can do it? I could look at them and see if they’ll work in XOD world. This function creates a new instance of the Stepper class that represents a particular stepper motor attached to your Arduino board. This program drives a unipolar or bipolar stepper motor. A transaction in XOD is analogous to loop() (clock set to always), but I wonder if that’s fast enough to create smooth motion, given the rest of your program? What are the timings needed for that (when do you need to send the next pulse, with what tolerance)? Techniques based on “pulsing” every loop() seem problematic. But, there are a limited number of those, and they are used for multiple things. Please watch the first 14 minutes of the following video to understand the three excitation modes of the bipolar stepper motor: Step 2: Recognize the Names of Your Stepper Motor Wires. The problem was timing, if you want continuous/smooth movement, which needed to be tight, and thus (probably) use interrupts. Step 1: Understand How Bipolar Stepper Motor Works. Yes, I was trying to remember the discussion about multiple-steppers.
