| Feb 22, 2023 at 0:49 | comment | added | Milliways | You seem to have an issue with 3.3V pins (this depends on your wiring) Gnd is preferable. | |
| Feb 22, 2023 at 0:47 | comment | added | Milliways | Either works (there are subtle reasons to prefer Gnd). What you have will work (remove the superfluous resistor). One way to improve noise rejection is to use low value pull. EACH pin NEEDS its own pull. | |
| Feb 22, 2023 at 0:29 | comment | added | m5c | I’m unsure how to follow up on the reply. Is the message that I should change the wiring to a pull-up as referenced in the elinux link (because: « pull up is normal engineering practice while pull down is not »?). Or is the message that I merely implemented the pull down wrong by placing the grounded resistor on the wrong side of the button? Could you please clarify? | |
