PC based Stepper Motor Control

[amit_smart]

I would like to know how we can control the speed of a stepper motor with the help of a computer.

connect youre stepper to the PCs lpt (printer) port and then get the pins high in a sequance and how fast you change it that fast youre motor will go

i've been doing that - till i hooked the pic up to them...

what i did was i built a circuit on an ISA wirewrap board...
i used pascal to talk to the board...
in the beginning i was having problems..but i got it working though..

the circuit is 3/4 down the first page..

I think you will have to program a .DLL file to operate your parallel printer port

if he's running Windows he will, windows likes to protect the printer port becuase of stability issues involved with it... you have to write some libraries to get around this.

Only if you're running NT based Windows (NT, 2000, XP), the Win95 based ones (95, 98, ME) don't require drivers to access the ports - you can simply 'bit bang' the ports regardless.

Try my Animated stepper controller.

And turn off the lights in the room.

Yes, good point, i often forget people still use win9x.
