Using ADC2 pins with Wi-Fi enabled as digital pins on ESP32
Posted: Fri May 24, 2019 4:58 pm
Hi, I need to connect an MFRC522 (RFID-Reader) to ESP32. Most contacts are busy, free contacts remain in the ADC2 section. I need to connect the SDA_SS and RST pins to any digital pins.
Question, pins 2, 4, 13, 25, 26, 27 - which are included in ADC2, can normally work as digital when Wifi is on? Or should they not be used?
