Mr. Scott Dattalo's debounce code is a work of
art.

After some experience with keys, switches, photo
cells and magnetic detectors, I denounce
everything in software.  everything....  Even
debounced a few software switches.

As the software denounce depends on timing, have a
constant time free running interrupt routine that
denounces all the input pins, and also outputs all
the updated output pins at same time.

Now to get on the SOAP BOX....

While Mr. Dattalo's debounce code is a work of
art, But "DON'T TRY THIS AT WORK".  Use the code,
but don't try to emulate the style.

You wrote....
>Take some time to fully understand it<

It would be very difficult to modify and if it
didn't work, would be hard to debug.  It would be
a nightmare to debug a page of code written in
this style, even if you wrote it a month ago.

Notice that it takes a web page to comment this
code?  I sort of have a rule that if it takes more
lines to comment a bit of code then the code
takes, then the code is too complicated.  When the
code is written and debuggeg, the programming job
is only half over.  Latter comes the
modifications.  Also the same code may be ported
to other programs.  And the time involved to write
the code could be excessive.

I am so impressed with this code that I tried to
port it to basic one time.
