Stepper Motor

Hello folks.
I did some search in the prop forum and could not find entries on interfacing Prop w/ Stepper Motors. Can someone point me to any advice on how one might do this in prop.

thanks in advance

    It depends on if you want to make a stepper motor driver or just inteface with a stepper driver. The latter is very easy, they normally have two inputs, one is called step and the other direction. You just pulse the step to make the motor step and set direction low or high to set the direction.

    Search for the term CNC and also mill to find some examples. Go to the parallax homepage and click the link to the google search, it works much better (but include the word propeller or you will get everything).

    Graham, thanks. That search route did the trick.

    I found a few urls. This PDF looks to be what I'm after

    That's driving the motors directly so the propeller has to generate the phase signals. You should read "jones on stepping motors" (google it) to learn more.
