Arduino 0012 for ATmega328P


ATmega328P seems to be almost identical to ATmega168, which is used in Arduino, except the flash memory space. This is not true if you are a firmware programmer. The header file ".../include/avr/iom328p.h" defines a little bit different macro symbols in comparison to the header file for ATmega168. From this point of view, ATmega328P is a family of ATmega168P, not ATmega168. The "P" suffix means the "picoPower" (tm) technology. We have to use "*_vect" symbols instead of "SIG_*" symbols for interrupt vectors. This is the reason the Arduino 0011 IDE for ATmega328P by does not work completely.
