Keong,
I know you asked about Software debouncing...
It sounds like you are only working with 1 button.
Is there any reason you can not put an RC on RB0 or the Switch?
Using a T of about 10ms could provide an equivalent 'Hardware debounce'
Guys, tell me if I am crazy in trying to slow the signal change?
I can not find any minimum or maximum rate of change in the spec sheet.
I know this delay would not want to be used coming from another chip,
but in human terms what is 50ms?
I have used this trick on a worn out mouse button that used to double
click every time.
