How to set the analog attenuation?

The code to set the esp32/arduino code to set the analog attenuation doesn't seem to work. Can anyone say how its supposed to be done? Or is there some bug in the SDK? Code is here: https://github.com/espressif/arduino-esp32/blob/master/cores/esp32/esp32-hal-adc.c#L69 Issue here: https://github.com/...

ADC max input voltage?

Hi, can anyone tell me the absolute maximum input voltage of the ESP32 ADC pins? I've seen a few blog posts suggesting 4.0 volts but I can't see that any any Espressif docs.

Also, does that change with the ADC attenuation setting?

Thanks!
