ESP32 + ESP … WebSome of the ADC2 pins are used as strapping pins (GPIO 0, 2, 15) thus cannot be used freely. Such is the case in the following official Development Kits: ESP32 DevKitC: GPIO 0 cannot be used due to external auto program circuits. ESP-WROVER-KIT: GPIO 0, 2, 4 and 15 cannot be used due to external connections for different purposes.
WebAdd ESP32 input interrupts to the GPIO input class created in ESP32 GPIO in C++ Part 1. In part 1 of this series, we created basic wrapper classes to easily access the GPIO functionality using C++ methodology. However, there are some IO features that we are not utilizing. In this tutorial, we are going to implement input interrupts for the ESP32.
