Problem jest dość dziwny, program się kompiluje jednak na wyświetlaczu nic się nie pojawia. Czyści ekran, inicjalizuje wyświetlacz i nic. Natomiast jeśli dotknę palcem pinu D7 - Wszystko jest OK. Pojawia się napis Test. Nie mam pojęcia czy to problem inicjalizacji wyświetlacza czy coś nie tak w kodzie.
