Differential Signal From Parallel Port? was created by Todd Zuercher
Is it possible to use two ordinary parallel port outputs to make a differential signal for a step/dir device? I was wondering if I could just connect two output pins to the same source such as this
net xstep => parport.0.pin-02-out => parport.0.pin-03-out-invertPlease Log in or Create an account to join the conversation.

That should work as long as the pins are on the same port and same parallel port register
(so they are updated simultaneously)
This would be the case as long as you chose the differential pairs from the
data pins (pins 2..9) or control pins (pins 1,14,16,17) on the same parallel port
