input capture with digital filter ?

[trimarco232]

Hi,
uno like arduinos have input capture with digital filter, on TIMER1
the filter is basic, ie. it waits for 4 samples having the same level (HIGH or LOW) before validate a level change, and immediately trigger a capture
somme mcus. (like the $0.1 ch32v003) have ICPs with filters witch one can select the sampling rate, and the number of samples
RP2040 looks to have nothing like this, unless it can be done with the PIO peripherals
is there an existing code for this ?
