rafal-bielsko Luty 1, 2012 Udostępnij Luty 1, 2012 Jeśli nie masz możliwości debugowania to zdefiniuj sobie jeden pin i podlącz tam diodę. Potem w programie wklej sobie w miejsce gdzie masz wątpliwości "ledon;" i będziesz wiedzieć gdzie program wchodzi a gdzie nie. Może w ten sposób trafisz na kawałek kodu który nie jest realizowany. Płytkę zawsze warto sprawdzić kilka razy ale bez przesady 🙂. Tu masz gotowe definicje dla PB0: #define ledon DDRB |= _BV(0);PORTB |= _BV(0); #define ledoff DDRB |= _BV(0);PORTB &= ~_BV(0); Cytuj Link do komentarza Share on other sites More sharing options...
