stepper motor ramp code

Zap-o

I am running a stepper motor driver that takes a PWM signal from the propeller and steps out a motor.

Does anyone have a ramp object written that will ramp a stepper motor?

Just dont want to reinvent the wheel.

Since you were not very specific on what type of driver you are looking for, this is just a shot in the dark. However, if you have a driver that simply requires a step pulse, take a look at this post, it works well for me. It can be tailored to suit your specific requirements. It can go from 0 to well past 15 revolutions per second, I am guessing maybe 20-25 revs per second. Read the whole post, because the driver has changed. The final function is the one to use.
