Der "große" ATMega,
  ATMEGa1284P
PDF als Kurzmanual: Kurz_Manual_ATMEGA1284P_XPLD_ATM.pdf
Ich habe eine UART Funktion gefunden in  https://github.com/andygock/avr-uart/

Ich verwende WinAVR-20100110 alös Programmierumgebung

ALT:
wozu es eine Patch gibt  (2009)
Allerding ist diese Seite schon von 2009 !!
DIESER SCHEINBT NICHT MEHR ERFORDERLICH ZUSEIN !!
Aufwärtskompatibel zu ATMegaX wie ATMega328 ( Arduino )
Patch für WINAVR: WinAVR-20060421-patch_MikroKopter.zip
Dies ist aus der Seite:   http://wiki.mikrokopter.de/Softwareentwicklung
http://www.mikrocontroller.com/files/WinAVR-20060421-patch_MikroKopter.zip
in makefile:   #MCU = atmega1284p
        F_CPU stellen nicht vergessen.
Leeres funktionierendes WINAVR Projekt mit UART !!
ATM1284_Leer.zip
   download, auspacken und in WAVR das Projektfile öffnen
