After (only after) I soldered the chip I got the feeling I made it wrong.
Where is pin#1 ?
If I keep the chip in such a way that i can normally read Atmel logo on it, is pin#1 on the up-left corner ? There is no mark on that corner.
On the top side there are two marks, like two circles, one bigger, one smaller. Is pin#1 near the big circle ?
