Hi!

I wish to control the speed of a stepper motor, with my basic stamp 2. and display that speed on a four digit led volt meter.

I know this topic must exist somewhere but cannot find it. Can someone help?

    I took the Parallax example code for the Unipolar stepper and added a PULSOUT (spd_pulse)·that gets executed with each "Do_Step".· So, that equivalent voltage (P0, pin_0) on a voltmeter will reflect the speed.· It's an extra program line, but by experimenting with values of PW (CON) and stpDelay, a transparent compromise should be practical.

    I'm sure that other options will evince forthwith.

    Thank you, P J Allen.
    That seems the simplest route many Thanks.
