ESP32 Forum

Many months ago there have been many posts about non-linear ADC characterisic.

Nowadays, ADC seems to be still something useless and no work has been done to fix non-linearities.

We're talking abouts errors close to 5-10% and sometimes more.

Is there any news on this issue?

ADC is very important for IoT applications....

Agreed. We're still working on it; hope to have the first code for it in esp-idf master within a few weeks.

Great! Thank you for your update!
