correct, but I would not dicount the mutiple uC possibility out of hand.

Of course. I'm also a fan of using multi micros to enhance and ease system performance. But from what Abhishek wrote

I searched for debouncing techniques here for quite some time. And I think that the easiest (of the inexpensive) technique is writing a debouncing program in a separate 8051 and make it into just a debouncer chip. It is more economic than the commercially available debounces (like max6818, which is not even readily available here in India) and does not take away processing speed from the main chip.


I assumed, that the only reason for using these slave micros was, that he hasn't found a fast and simple debouncing scheme yet.

Debouncing with an 8051 of 16 I/O pins            01/01/70 00:00      
   You don't need these slave micros            01/01/70 00:00      
      yes, but some more questions            01/01/70 00:00      
         Not scary at all...            01/01/70 00:00      
            In that case.....            01/01/70 00:00      
            here is the schematic            01/01/70 00:00      
               I would try shift registers            01/01/70 00:00      
               just a note            01/01/70 00:00      
                  The joke is:            01/01/70 00:00      
                     the reality is            01/01/70 00:00      
                     Re: The joke is            01/01/70 00:00      
      correct, but            01/01/70 00:00      
         I was assuming...            01/01/70 00:00      
   Bounce time of your relays?            01/01/70 00:00      
      Not very clearly            01/01/70 00:00      
         Bravo!            01/01/70 00:00      
   The original question            01/01/70 00:00      
      What's wrong with the shift register sol            01/01/70 00:00      
      HUH?            01/01/70 00:00      
         I am sorry            01/01/70 00:00      
            that was not the issue            01/01/70 00:00      
   why oh why oh why oh why            01/01/70 00:00      
      because it cost nothing            01/01/70 00:00      
         yeah right            01/01/70 00:00      
            yes, they do            01/01/70 00:00      
            Design is a state function            01/01/70 00:00      
               All the more using shift registers!            01/01/70 00:00      
                  I think your solution is better            01/01/70 00:00      
                     I guessed so...            01/01/70 00:00      
                  hidden part            01/01/70 00:00      
                     I can see a 'lucky sample' of a shift re            01/01/70 00:00      
                     True, but...            01/01/70 00:00
