| Supported Targets | ESP32 | ESP32-C2 | ESP32-C3 | ESP32-C5 | ESP32-C6 | ESP32-H2 | ESP32-P4 | ESP32-S2 | ESP32-S3 | | ----------------- | ----- | -------- | -------- | -------- | -------- | -------- | -------- | -------- | -------- | # 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. ## Example Output ``` I (0) cpu_start: Starting scheduler on APP CPU. I (326) example: Create timer handle I (326) example: Enable timer I (336) example: Start timer, stop it at alarm event I (1336) example: Timer stopped, count=1000002 I (1336) example: Set count value I (1336) example: Get count value I (1346) example: Timer count value=100 I (1346) example: Disable timer I (1346) example: Enable timer I (1356) example: Start timer, auto-reload at alarm event I (2356) example: Timer reloaded, count=2 I (3356) example: Timer reloaded, count=2 I (4356) example: Timer reloaded, count=2 I (5356) example: Timer reloaded, count=2 I (5356) example: Stop timer I (5356) example: Disable timer I (5356) example: Enable timer I (5366) example: Start timer, update alarm value dynamically I (6366) example: Timer alarmed, count=1000002 I (7366) example: Timer alarmed, count=2000002 I (8366) example: Timer alarmed, count=3000002 I (9366) example: Timer alarmed, count=4000002 I (9376) example: Stop timer I (9376) example: Disable timer I (9376) example: Delete timer ``` ## Troubleshooting For any technical queries, please open an [issue](https://github.com/espressif/esp-idf/issues) on GitHub.
