# 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.
