# 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](https://idf.espressif.com/) for all the steps to configure and use the ESP-IDF to build projects.
