Hello, I see red squiggly lines under #include <Arduino.h>. The project will build but obviously this is not ideal. I have seen a few other posts with similar issues but no real resolutions were provided. Any idea where to start with troubleshooting this? Thank you.
What’s in your `platformio.ini’?
i.e. for a Arduino Uno it would look something like…
[env:uno] platform = atmelavr board = uno framework = arduino
Sounds like my issue, which was solved by deleting the .vscode directory in the project folder and restarting vscode.
I have the same problem.
