How to use parport2 for input mod?

Why do you want to use encoders as feedback with steppers?
Do you want the encoder feedback just to cause an following error if it detects missed steps
Or do you really want full closed loop control where EMC uses the encoder to drive the motor speed?

Yes, I want the Encoder feedback just to cause an following error if it detects missed steps.

reading encoders in software could really limit your max speed as it's fairly easy to move them faster then the computer can read them
and also finding a low latency computer becomes more important again so as not to limit top speed too much.
What is the resolution of the encoders? I mean how many pulses per rotation?

Resolution per Rotation is :
support : 1 ,2, 5,10 ,12, 15 , 20 , 23 , 25 ...3000, 3600, 5000,6000,8000 (R/R)
