ESP ADC CAL
Posted: Wed Mar 06, 2019 7:35 pm
Hi guys, I would like to understand more deeper about esp_adc_cal() library.
I've always read in places that use the Vref or TP values recorded in eFuse, but I tested it on a board without both, which makes the library use the standard Vref, but it still worked so well that made me wonder how it works. I see some tables in .c file, but would to understand little more (technical explanation)...
