Floating input pin issue [solved]

[FFT]

I liked the method.

But there is a problem, when the pin is low and button pressed, there is 10mA extra current consumption.
I making the pin low all the time looks a bit problematic in that case.

What if I put the pins as inputs all the time, but discharge them on every 10ms time (output->low->input) before reading the input, then make the pin input again?
One step further is to discharge the pin when button is not pressed only. So no any extra current drown.

Can this method help too?

Thanks

Problem then is that the floating pin will be prone to EMI. Pins should never
really be left floating. The solution that avoids the extra current, is:

[FFT]

Tested it.
This method works very nice even with low debounce time.
Thank you for your help.
