Makefile abändern von ATMega32 zu ATMega644p

[Carmen (Gast)]

Hallo Forum,

Ich habe ein Mikrocontroller ATMega32 mit einem Makefile. Programmieren 
tu ich mit Eclipse und gcc. Alles funktioniert ohne Probleme, nun würde 
ich gerne auf den ATMega 644p umsteigen und muss natürlich das Makefile 
anpassen, kann mir jemand sagen wie ich das am schnellsten mache?

vielen Dank im voraus

mmcu ersetzen sollte reichen (zumindest was das Makefile angeht).
