I moved your topic to an appropriate forum category @nhkhanh.

In the future, please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.

This is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.

Thanks in advance for your cooperation.

Hi @nhkhanh. I'm going to ask you to post the full verbose output from a compilation.

This procedure is not intended to solve the problem. The purpose is to gather more information.

Please do this:

1. Select File > Preferences... (or Arduino IDE > Settings... for macOS users) from the Arduino IDE menus.
   The "Preferences" dialog will open.
2. Check the box next to "Show verbose output during: ☐ compilation" in the "Preferences" dialog.
3. Click the "OK" button.
   The "Preferences" dialog will close.
4. Select Sketch > Verify/Compile from the Arduino IDE menus.
5. Wait for the compilation to fail.
6. You will see a "Compilation error: ..." notification at the bottom right corner of the Arduino IDE window. Click the "COPY ERROR MESSAGES" button on that notification.
7. Open a forum reply here by clicking the "Reply" button.
8. Click the <CODE/> icon on the post composer toolbar.
   This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
   
9. Press the Ctrl+V keyboard shortcut (Command+V for macOS users).
   This will paste the compilation output into the code block.
10. Move the cursor outside of the code block markup before you add any additional text to your reply.
11. Click the "Reply" button to post the output.

In case the output is longer than the forum software will allow to be added to a post, you can instead save it to a .txt file and then attach that file to a reply here:

1. Open any text editor program.
2. Paste the copied output into the text editor.
3. Save the file in .txt format.
4. Open a forum reply here by clicking the "Reply" button.
5. Click the "Upload" icon () on the post composer toolbar:
   
   The "Open" dialog will open.
6. Select the .txt file you saved from the "Open" dialog.
7. Click the "Open" button.
   The dialog will close.
8. Click the "Reply" button to publish the post.

Alternatively, instead of using the "Upload" icon on the post composer toolbar as described in steps (5) - (7) above, you can simply drag and drop the .txt file onto the post composer field to attach it.
