Issue/Bug report template

Before reporting an issue, make sure you've searched for similar one that was already created. Also make sure to go through all the issues labelled as Type: For reference.

Finally, if you are sure no one else had the issue, follow the Issue template or Feature request template while reporting any new Issue.

External libraries compilation test

We have set-up CI testing for external libraries for ESP32 Arduino core. You can check test results in the file LIBRARIES_TEST. For more information and how to add your library to the test see external library testing in the documentation.


We welcome contributions to the Arduino ESP32 project!
