Peter; I had to do an is_inverted to the 2 gpio's that were stepgen 3's outputs.
But the waveform indicates its open drain, so the off, top of the waveform is being left open to get back to high, taking several tens of microseconds. Is there something I can put into hal file to restore the active pullup? The second thing I noticed is that the pulse trains aren't steady, with discontinuities enough (20%) to putz with the torque of a stepper, making it stall quite easily at speeds well prior to its top speed. Is there anything I can do about that? Thanks Peter. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
