[Premium-Rx] 3030 keypads

Tue Jul 1 17:02:23 EDT 2003

I may be a off on this but I would think a hardware debounce would be much
more effective than software debounce because:
1. it's a hardware feature that's not wanted or a malfunction..
2. hardware would be faster!
3. firmware would be the second choice..
4. don't waste software doing something that easily done in hardware unless
you've got the resources and may need bounce later..
5. when would anyone want bounce or the ability to control it in software?

tnx
