Linearity of esp 32
Posted: Thu Jun 08, 2017 5:43 am
I have read about the linearity issue on esp forums.
I recently did a test on it and found the following result (I am using the analog read function on the arduino IDE) :

the excel sheet attached has the input value and the output no. of the esp.
It is pretty linear above 1V however the below that it is quite non-linear.
Is there a way to solve this issue?

Has the look up table been included ? If not by when can we expect the issue to be solved?
