Ich weiss es ist nur der dev branch (und den soll man ja nicht produktiv nutzen) aber ich vermute dass das so nicht gedacht ist 
Ich bin gerade auf der Suche warum mein Akku eigentlich dauernd leer ist - daher wars einen Versuch wert. Leider bin ich in C++ nicht so richtig firm - das überlasse ich euch Profis
Vermutlich sind alle Fehler mit dem error: reference to 'byte' is ambiguous verbunden. Dort soll man sich zwischen enum class byte : unsigned char; und typedef uint8_t byte; wohl entscheiden.
