Button Example
This example shows how to use the espp::Button
class to handle input events
from a physical button connected to an ESP32 GPIO pin.
How to use example
Hardware Required
This example is designed to be run on an ESP32 board which has a digital button connected to GPIO2 of the ESP32, with the button having a hardware pull-down resistor so that its resting state is logic low and its active / pressed state is logic high.
Build and Flash
Build the project and flash it to the board, then run monitor tool to view serial output:
idf.py -p PORT flash monitor
(Replace PORT with the name of the serial port to use.)
(To exit the serial monitor, type Ctrl-]
.)
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
