ESP32 Ananlog Pins #19767

Hi, i'm using tasmota (precompiled binary v13.1.0.4) with a ESP-WROOM-32 development board. I'm wondering why there are only four ADC GPIO pins (gpio34, gpio35, gpio36, gpio39) available in Tasmota. Following the ESP-32 datasheet there are a lot more analog pins. I've tested them with a small test script. In tasmota they are selectable and show up in web interface but always show the same value. Is there any way to bring these pins into tasmota? |

One reason is that the ADC2 block is not workable with Wifi, and therefore not supported by Tasmota. But you can use the pins of the ADC1 block, assuming that you have a board where gpio 32-39 are broken out. That's not the case on all dev boards. |
