# Example: ESPTimer C++ class (See the README.md file in the upper level 'examples' directory for more information about examples.) This example demonstrates usage of the ESPTimer c++ class in ESP-IDF. In this example, the `sdkconfig.defaults` file sets the `CONFIG_COMPILER_CXX_EXCEPTIONS` option. This enables both compile time support (`-fexceptions` compiler flag) and run-time support for C++ exception handling. This is necessary for the C++ APIs. ## How to use example ### Hardware Required Any ESP32 family development board. ### Configure the project ``` idf.py menuconfig ``` ### Build and Flash ``` idf.py -p PORT flash monitor ``` (Replace PORT with the name of the serial port.) (To exit the serial monitor, type ``Ctrl-]``.) See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects. ## Example Output ``` Setting up timer to trigger in 500ms timeout Setting up timer to periodically every 200ms periodic timeout periodic timeout periodic timeout periodic timeout periodic timeout ```
