Topic: Looking for Arduino coder for 2 bipolar motor accel/decel control (Read 102 times) previous topic - next topic


I need to control 2 bipolar motors such that they accel/decel smoothly using a  non linear rate, ie S-curve.  I want each motor to do the following, independent from the other:

1) Accelerate from 0 to (x) number of steps/second over (y) number of steps
2) Maintain constant speed  of (x) steps/second for (z) number of steps
3) Decelerate from constant speed (x) steps/sec to a slower constant speed of (m) steps/sec over (n) number of steps
4) Maintain constant speed of (m) steps/sec for (o) number of steps
5) Accelerate from (m) steps/sec to (p) number of steps/sec over (q) number of steps
5) Decelerate to 0 over (r) number of steps

The user specified values are in ()

I have used the AccelStepper library to do the above with some success with a single motor, but I am now having trouble with doing the same for 2 motors.

Anyone interested in writing the code for me? If so, I look forward to hearing from you!
