Hi Antonio, what about CNC drivers that require
the industry standard step/dir pulses that
must be at exact and often quite high frequencies?
Like 3 pulse streams of differing f at 10kHz to
40kHz that need exact pulse timing?
There is only a few bits, but high speed timing
Would USB handle this? This is quite possible
through parallel port in dos environment but I
would be worried about timing using USB..?
