Hi all, I would like to programm an ATMEGA 328P-PU like in this link: http://arduino.cc/en/Tutorial/ArduinoISP.
Can i use an external oscillator or have i to use the internal one?

A virgin atmega328p chip will use the internal oscillator, which make programming it really easy. It is only after you have changed the fuse bytes to require a crystal/ceramic resonator or an external oscillator that you need to worry about providing those components or the external clock.
