I2C default pins as GPIO 21 and 22 ?

Postby Kalki123 » Wed Dec 13, 2017 9:51 am

Is there any particular bit set by default in ESP32, internally sets GPIO 21 and 22 as I2C pins. Even though i am using GPIO 21 as interrupt pin(push button) and GPIO 22 as normal GPIO(LED)?

Whenever i use both I2C and interrupt code, i get I2C read error.
