Button Power Save Example

This example demonstrates how to utilize the button component in conjunction with the light sleep low-power mode.

• button Component Introduction

Hardware

• Any GPIO on any development board can be used in this example.

Build and Flash

Build the project and flash it to the board, then run the monitor tool to view the serial output:

• Run . ./export.sh to set IDF environment
• Run idf.py set-target esp32xx to set target chip
• Run idf.py -p PORT flash monitor to build, flash and monitor the project

(To exit the serial monitor, type Ctrl-].)

See the Getting Started Guide for all the steps to configure and use the ESP-IDF to build projects.
