Need Library source

Hi @Farticus. The problem is that this library is not formatted as an Arduino Library.

If you want to give it a try, it can be installed with simple adjustment to the file structure. I didn't look to see whether it is compatible with Arduino, but if you want to give it a try I'll provide instructions you can follow to install that library:

  1. Select File > Preferences... (or Arduino IDE > Settings... for macOS users) from the Arduino IDE menus.
    The "Preferences" dialog will open.
  2. Take note of the path shown in the "Sketchbook location" field of the dialog.
  3. Click the "CANCEL" button.
    The "Preferences" dialog will close.
  4. Click the following link to open the library's GitHub repository homepage in your web browser:
    https://github.com/noassemblyrequired/esp32-ds3231
  5. Click the "Code ▾" button you see on that page.
  6. Select Download ZIP from the menu.
    A download of the ZIP file of the library will start.
  7. Wait for the download to finish.
  8. Extract the downloaded file.
  9. Move the ds3231.h file from the include subfolder of the extracted folder to the root of the extracted folder.
  10. Rename the ds3231.c file that is located the root of the extracted folder to ds3231.cpp.
    ⓘ This is done because the .c file extension causes the library source code to be compiled as C programming language, while the .ino files of your Arduino sketches are compiled as C++. You can use objects from C libraries in a C++ program, but you need to do something special in your sketch code to accomplish that. So I think it is more simple to just rename the source code file with the .cpp file extension so that it will be compiled as C++ instead of C. C++ is a superset of C, so this shouldn't cause any problems.
  11. Copy the extracted folder to the libraries subfolder of the path you saw in the "Sketchbook location" preference.
    The folder structure of the installation must look like this:
    <Sketchbook location>/
├── libraries/
│   ├── esp32-ds3231-main/
│   │   ├── ds3231.cpp
│   │   ├── ds3231.h
│   │   ...
│   ...
...
    (where <Sketchbook location> is the path from the Sketchbook location" preference)
  12. Select File > Quit (or Arduino IDE > Quit Arduino IDE for macOS users) from the Arduino IDE menus.
    All Arduino IDE windows will close.
  13. Start Arduino IDE.
