hello,

i am playing with 16f628a @20mhz and trying to use timers(0 or 1) as asynchronus counter.
i mean, is it possible to count a signal independent of the system clock.
i am not sure if that is possible or how to do.

if possible:
can you give me an example for that?
if not:
why there is a source selection?

another thing:
if i understand correctly Timer0 of AVR has 1:1 prescaler but Pics are 1:2 at lowest, right?

i have another question about LCDBacklight constant(?).
what is it for?, why not just define a pin and set it on/off?

btw, i am using the latest GCB version

This topic was recently talked about in terms of a frequency meter using a 12f683 and TMR0 via the external input T0CKI pin. https://sourceforge.net/p/gcbasic/discussion/579126/thread/8b1aa325/

That should get you going. Also, can use the comparator to condition the input signal if required.

i saw that topic.
i am trying to copy and implement your code w/out understanding.
however, it is 02:30 am right now, i need a fresh mind
thank you again
