So after some testing, the pin n°19 is always at -0,7volts which is not nice...
Do i have to replace the 40 pins chip?
Looks strange to me, how a chip can work for everything else but not that?
Also, how to know if it is a 8mhz or 16mhz? in arduino, the 8mhz doesn't seem to work so i guess it is the 2nd one...
By the way thanks for your very clear answer.
