Adding DebounceThrottleDiv define to slow down the debounce rate.

Adding DebounceThrottleDiv define to slow down the debounce rate.

By default:
DebounceThrottleDiv = 0;
This is the default infinity behaviour right now (may be changed in the future).

Increasing DebounceThrottleDiv will increase the scan rate divider.
DebounceThrottleDiv = 1; # Scans half as much
DebounceThrottleDiv = 2; # Scans a quarter as much
DebounceThrottleDiv = 3; # Scans an eigth as much
etc.

For ARM based uCs (like the Infinity) the maximum divider is 32.
