diyelectromusic, 27 days ago Ok, so first major ramification of ignorance is forgetting that the ESP32 has Strapping pins - GPIOs that are internally pulled high or low on boot. I've managed to choose three of them for my genuine analog inputs - whoops! I think I can work around it, but it does mean that the pulldown resistors in my CV circuit aren't really working properly. Any thoughts? This the circuit - so what would an internal ~45K pullup/down add to this - should I just go for a stronger external pull-down?
