java error

Windows 10, Arduino 1.8.10 tried 3 different boards and a variety of sketches, uninstalled and reinstalled IDE, no change

When trying to up load sketches I get the following error:

Global variables use 9 bytes (0%) of dynamic memory, leaving 8183 bytes for local variables. Maximum is 8192 bytes.

These are only one aspect of the possible issue.

Add the Arduino directories to your antivirus / anti malware / other security exclusions.

So that would be at least two of the following.

C:\Program Files (x86)\Arduino
C:\Users\yourname\AppData\Local\Arduino15 (depends on IDE install type/location)
C:\Users\yourname\AppData\Roaming\Arduino15 (depends on IDE install type/location)

If you have your sketches set up in a different location it’s also worth adding that directory to the exclusions also.

Additionally if you also use the online IDE “CREATE” the following directories.

C:\Users\yourname\AppData\Roaming\ArduinoCreateAgent
C:\Users\yourname\AppData.arduino-create

If you have installed to a different drive swap the drive letter as needed.
If you also have an unzipped IDE installed that path should also be added to exclusions.

Well tried all of this, no success.

This error indicates you need to take some drastic action. Be aware this is somewhat advanced and will remove any boards you have installed via Boards Manager:

  • In the Arduino IDE, click the link on the line following File > Preferences > More preferences can be edited directly in the file. This will open the Arduino15 (or similar name depending on OS) folder.
  • Delete all files and folders under the Arduino15 folder except for preferences.txt. Please be very careful when deleting things from your computer. When in doubt, back up!
  • Restart the Arduino IDE

Verify that you can now use your board before reinstalling any packages via Boards Manager.

Thanks much. That did it. Everything seems to be working fine now.

You're welcome. I'm glad to hear it's working now. Enjoy!
