I have a question for you!
I need to control stepper motor driver with the parallel port. I'm able to do that with VISA or the Out.vi.
I need to go at 1kHz for example. But i'm juste able to go with VISA at 500 Hz and with out.vi at 200 Hz.
How I can go faster ???
You can see my code below. For the frequency, I put a timer . When i'm going faster then 200 Hz the frequency seem not to be what I hope! For example 340 Hz give to me 498 Hz, but at slowly frequency everything is ok.
Thanks For all
P.S. Sorry for my english!!
