Good afternoon,
I am trying to use the ADC in one shot mode on ESP32-S3.
I have use the One_Shot Read example and I use calibration in Curve Fitting Mode.
(It seems that it is the only mode available on the Esp32-S3 - I use the Esp32-S3-DevKitC-1 board).
My problem is that even if I calibrate the ADC, it seems that the Read value cannot go further than 3137mV.
Do you think it is possible to go further than this value ? Maybe something like 3,3V max ??
Thank you for your help,
Best regards,
Thomas TRUIHE

I think it is difficult.
But you can use a voltage divider made up of two resistors, about 100K. If the transducer has a large value of output impedance, the voltage divided resistor should be larger.
