    I can’t seem to get this thing working. I’ve hooked it up to an arduino as suggested in other posts. With an external power supply of 12v. The stepper motor simply jitters back and forth. All 4 variations of the MS control pins result in jittering.
    When I looked at the outputs on an o-scope I noticed that the wave forms didn’t correspond to those listed on the datasheet for the A3967.
    Any suggestions?

No public wish lists :(
