GPIO

Learn how to use the ESP-IDF button component to handle GPIO buttons with event detection, debouncing, and callbacks. A step-by-step guide with practical code examples.

In this article, we explore how to configure GPIO pins as inputs in ESP-IDF and discuss the importance of pull-up/pull-down resistors. We will try two approaches for reading GPIO values: polling and event-driven interrupts, showing how to implement each method effectively.

This article explains how to configure and control GPIO pins on Espressif SoCs, covering push-pull and open-drain output modes, drive capability, and library usage. It then provides a hands-on example of blinking an LED using gpio_set_direction and gpio_set_level on a ESP32-C61-DevKitC.
