Timer0 Timer1 Timer2 ADC Comparator Hepsi bir arada örnek uygulama

 Timer0 Timer1 Timer2 ADC Comparator Hepsi bir arada örnek uygulama.

timer0 zamanlayıcı , timer bir sayıcı, timer2 sabit frekans zamanlayıcı 133ms olarak sabitlendi

analog giriş ile voltaj ölçümü. Comparator iler 2.81 volt çıkışa ayarlandı.
