I'm guessing we need a 

#define __SAM3X8E__

in there. I'll see if I can fix it.

nseidle commented 6 years ago

I was wrong. There's a const array that then gets memcpy'd. The compiler options for the SAM series are stringent enough that this throws an error. Removing the const removes the error. Pushing new version to library manager. Please let me know if you continue to see issues.
