Example: General Purpose Timer

This example illustrates how to use gptimer APIs to generate periodic alarm events and how different alarm actions behave on events.

How to Use Example

Hardware Required

  • A development board with ESP SOC chip
  • A USB cable for Power supply and programming

Build and Flash

Run idf.py -p PORT flash monitor to build, flash and monitor the project.

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

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