I switched to the ZIFDuino mostly because it's nice not to have a pile of wires.


Sure, this setup looks a bit messy ^_^ I was thinking about using a soldered board, not a breadboard, without the Arduino, just the programmer and some power. I haven't understood yet if Atmel µC usually *required* an external oscillator/resonator... But I'll give a closer look to all these points when I'll have started working on it. I'm currently too busy with too many stuff to begin working on this.

No, the ATmega168 includes in internal 8MHz rc-oscillator (which is /8 for 1MHz initially).
The Lilypad firmware will run correctly on boards with the internal oscillator, for NG/Diecimilla compatibility you need a 16MHz clock of some kind.
An additional caveat, once you've fused a chip for some sort of external clock, you'll need to either use an external clock during programming or use parallel programming to rescue the IC.

Atmels long shunning of internal resonators means most ATmega designs use one, even if they could have used the internal RC clock.

So this is great ^^ I was just talking about building a board for programming only, so it's gotta be very easy to do.

My goal is to achieve to code without the Arduino libraries, to be able to keep Arduino stuff for fast prototyping, and finalize the projects on autonomous boards with no more reference to the Arduino lib. Not really a necessity, but I like the idea of digging a little bit more inside.

Many thanks for your answer.
