I've read several tutorials and the like on this, but I'm still a bit confused. If I want to drive an AVR with a 3.6864 MHz crystal and I find one on digikey that states 18pF load capacitance, I should give it ~26pF-32pF (depending on what's taken for Cstray on the board) correct?
This is what I gathered from the various discussions I've found. The reason I was questioning it is that on tuxgraphics.org, the avrusb500 specs show 18pF caps on the crystal. Since I can only seem to find crystals with 18pF or 20pF Cload, I assume that either I'm mistaken and Cload is the value of the caps, or Guido is mistaken and those values should have been higher...
