Software malfunction !!!

Hi,
In this case you have a hardware problem ,usually this type of problems if you have relays on board or inductive loads generate emc situations.
Power supply of the microcontroller should be stable if there is no separate reference voltage for adc , pcb signal routing for adc should respect some rules , ground loops and so on...

I'll check the hardware again.

As I told you, I reproduced the program in both Microcip Studio and mikroC for AVR. I also checked the hardware. Eventually I succeeded, I had a code error in both compilers and for this reason everything did not work properly. Now it works well on both mikroC for AVR and Microcip Studio.
