when i upload a Sketch to an UNO WiFi Rev 2, i get the following error:
"avrdude:WARNIG:invalid value for unused bits in fuse "Fuse5", should be set to 1 according to datasheet. This behaviour is deprecated and will result in en erros in future Version. You probably want to use Oxcd instead of Oxc9(double check with your database first."
i have no idea what it mean.
