Code is free, parts cost money/take up PCB space/break/etc. Switch debouncing in software is easy, free, and can be made into a function or subroutine to be called any time you need it, no matter how many switches you have to debounce. Remember my mantra: The ideal hardware design uses zero parts. You may not make it there, but the closer you get the better off you are. 8-) 73, Dale - N0XAS -- It's a thankless job, but I've got a lot of Karma to burn off.
