#127481 - debounce always !
Responding to: ???'s previous message
Jez Smith said:
If your application only need to know that a button has been pressed it doesnt need debouncing


Thats nonsense.

Debouncing was also useful in such a case to be sure, that the button was pressed in reality.

Otherwise electrostatic discharge or other noise may cause false detection of a still released key.
