GPIO4 analogread at 4095 all the time

Hi,

I am working on a project running on ESP-C3-13 module that read analog data from voltage splitter. The value is reading 4096 even voltage level is at 2.95v. I assure you that voltage level at pin is correct. What may cause the problem?

Thank you for your support.

Hi folks,

The reason is ADC_ATTEN_DB_11 0 mV ~ 2500 mV.
