Hi I am trying to use a push button to trigger the external interrupt of RB0. However I need to implement a s/w deboucing in my code to prevent multiple triggering of the interrupt. How do I go about writing the code for the s/w deboucing? (using delays?) __________________________________________________ Do You Yahoo!? LAUNCH - Your Yahoo!
