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. WebGPIO34-39 can only be set as input mode and do not have software pullup or pulldown functions. There is also separate “RTC GPIO” support, which functions when GPIOs are routed to the “RTC” low-power and analog subsystem. These pin functions can be used when: In deep sleep. The Ultra Low Power co-processor is running.
