Error compiling for board Arduino Nano 33 BLE.
Posting a fragment of the error output and then a screenshot of a fragment of the error output is very unhelpful.
Please do this:
(In the Arduino IDE) click File > Preferences
Uncheck the box next to "Show verbose output during: > compilation
Click "OK"
Sketch > Verify/Compile
After the compilation fails you'll see a button on the right side of the orange bar "Copy error messages". Click that button.
In a forum reply here, click on the reply field.
Click the </> button on the forum toolbar. This will add the forum's code tags markup to your reply.
Press "Ctrl + V". This will paste the compilation output between the code tags.
Move the cursor outside of the code tags before you add any additional text to your reply.
If the length of the output exceeds the forum's 9000 character limit, save it in a .txt file and post it here as an attachment. If you click the "Reply" button you'll see the "Attachments and other options" link that will allow you to make the attachment.
