Hi ESP-community,
ESP32-S3 has two different net labels for the Analog power domain: VDD3P3 and VDDA.
VDDA is shown in the power scheme below (from the datasheet of ESP32-S3 Series) :

But VDD3P3 is shown nowhere. I've looked into the datasheet, the manual and the hardware ...

ESP32-S3: Interpretation of the ADC characteristics and calibration results
Dear community,
The esp32-s3 adc's INL is specified as ±8 LSB, see below:

Is that specification based on the best straight line method or on the end point method?
I've applied a voltage ramp from 0 to 1.1V(=Vref), with 10ms stabilisation time foreach step and 10 samples for averaging ...

Re: Problem - Adding an existing ESP-IDF framework to ESP-IDF Manager
Hello,
I encountered a similar issue and will share my workaround.
It could be a workspace setting issue, so look for your active workspace folder in your file-explorer. Open the "tool_set_config.json" file. Inside that json is a list of the ESP-IDF versions you've installed. You need to check ...
