Hardware digital counter


#1

I need to read a tach presented as a stream of digital pulses.

I would prefer not to do this in software even though I could easily implement an interrupt. The pulse rate could be 2-300 hz and I’d prefer the cpu cycles to be focused more on the UI than on counting pulses.

Is there an input that could be used for this purpose? If not, I’ll take a look at building a counter chip into a module.

Thanks, Mark.

You can use the processor’s built in timers but this is very advanced and you need to know plenty to do so.

It sounds like you at Jacques may have similar projects…
