Hello People,
in my board with micro ATmega8535 the analog
input ADC6 (PA6) works beetween +5Vdc and 0Vdc
if for a mistake there is a bridge to the GROUND --->
the micro makes strange things (set ouputs, do not read inputs ...)
do you never had a similar experience ?

Hello,

The Signal you are sending to PA6 is refered to Ground? It should be, so a 0V is the same as ground. By the way you explained the problem it seams to be that the signal is not refered to the AVR ground (in fact to the AGND).
