Arduino in den Schalf schicken und mit Interrupt Pin aufwecken??

Hi,

ich möchte gerne immer wenn ein Pin-Falling an Pin 3 entsteht per RF12 eine Nachricht verschicken und dann wieder in den Schlaf gehen. Dafür habe ich folgenden Quellcode geschrieben. Der aber läuft nur ständig abstürzt. Vielleicht kann jeman den Code ja für mich optimieren.

Vielen Dank.

Gruß kami
