If one were to e.g. have a group of buttons feeding a 74HC165 shift register, and they had the "dubious resistance" problem I mentioned, hardware to help with the debouncing would need to happen before the shift registers (though such hardware could perhaps take the form of pull-ups that could selectively pull to 2.8 or 3.3 volts). | |
