ADC keyboard and fast response to user input, possible?

[CuriousOne]

So what I need.
if user presses key, there should be immediate response, but if he keeps it pressed, variable value should increase slowly, so he won't skip desired value.

I would try something like this. Of course, you have to

define var key
K_None con 0
K_Inc con 1
K_Dec con 2

AdcSub:
        ADCIN 0,x
        if x = $FF then key = K_None
        if x < 125 then key= K_Dec
        if x > 130 then key = K_Inc
return


MAINCODE:

      Gosub AdcSub
      if key = K_Inc then 
            y=y+1
            goto Mydelay
      endif
      if key = K_Dec then 
            y = y-1
Mydelay:
            pause 100
      endif
      Gosub Display
goto Maincode

Hi,

What's YOUR time lag for " immediate " ...

as always, this is a highly subjective point of view ...

Generally ... " immediate " means ... Interrupt !

Knowing your general way of thinking ... that probably could be much slower than a few microseconds ...

just consider the time spent between your thinking you must strike a key, and the act of striking the key, may be add the time needed to analyze the info that decide you to strike wich key , plus the time to define as a target the right key ... : interesting point of view, no ???

" immediate ", you told ???

LOL.

Do you have at least TV remote at hands?

when you press say channel up button, it immediately switches the channel (the actual change might occur a bit later, but here we're talking about system response), but if you keep it pressed, it will slowly cycle between channels.

So I think I should do the code in the following way:

Once key is pressed, start counter, say to 100, and do pause 1 inside it. If user releases key before counter hits 100, then do the action. But if user keeps key pressed and counter reached say 200, do the action, reset counter and start again.
