Hi there. I'm new here, so I'm not sure if this is the right group.
I've got something that outputs pulses per rotation. It uses a sine wave. I
planned on using (half of) an LM393 to convert it into a square wave, the trying
to read that into a parallel port so I can run a real-time display.
Now, the question is, how do I read the frequency (it ranges from 0 to about 150
pulses per second) into the PC so it's useable? I don't know assembler, but from
what I can tell, it's a low enough sampling rate that I should be okay with
something less robust like Basic or VBasic or something.
My extent of parallel port programming is turning on and off an LED in Basic.
Thanks in advance,
Kris
