Siema
Mam problem z kompilacją szkicu dla wyświetlacza RGB. Znalazłem w sieci poradnik krok, po kroku, jak uruchamić taki wyswietlacz jako stację pogody, ale poległem na kompilacji szkicu. Nie ukrywam, że jest to moja pierwsza styczność z arduino, ale udało mi się wgrać kilka przykładowych grafik, więc podstawy juz opanowałem. Utknąłem na błędzie, na którego nie moge znależć rozwiązania w sieci. Jak się domyślam, problem jest z plikiem <kongtext4pt7b.h>. Ten plik musiałem dodać ręcznie do biblioteki Adafruit GFX, bo nie było go po instalacji biblioteki.
Mam problem z kompilacją szkicu dla wyświetlacza RGB. Znalazłem w sieci poradnik krok, po kroku, jak uruchamić taki wyswietlacz jako stację pogody, ale poległem na kompilacji szkicu. Nie ukrywam, że jest to moja pierwsza styczność z arduino, ale udało mi się wgrać kilka przykładowych grafik, więc podstawy juz opanowałem. Utknąłem na błędzie, na którego nie moge znależć rozwiązania w sieci. Jak się domyślam, problem jest z plikiem <kongtext4pt7b.h>. Ten plik musiałem dodać ręcznie do biblioteki Adafruit GFX, bo nie było go po instalacji biblioteki.
