I'm trying to write a program like Mach3Mill that controls LPT servos. Now I use C# and library inpout32.dll to send data to LPT. The main problem is to make moving smooth like the original program does.
Now I'm sending data in loop changing data bit from 1 to 0 with intervals using Thread.SpinWait because Thread.Sleep produces larger intervals.
Are there any ways to send data with selected frequency?
