co należy zmienić w kodzie z greenbooka aby wykorzystywać bibliotekę do SSD1963 bez karty pamięci. Potrzebuje tylko znaków które są zapisane w pamięci flash uC. Kod gotowy z książki się kompiluje, jednakże gdy zmieniam:
[syntax=c]//************************ jeśli korzystamy z kart pamięci i Petit FAT
// *************************** deklarujemy 1
// *********************** jeśli nie korzystamy to
// *************************** deklarujemy 0
#define USE_PETIT_FAT 0[/syntax]
na wartość 0, kompilacja nie przechodzi. Zaznaczam że funkcje main i while mam praktycznie pustą, sama inicjalizacja.
błąd w eclipse:
[syntax=c]16:53:55 **** Incremental Build of configuration Release for project LCD_project3 ****

W kodzie pododawałem tylko przedrostki "const" tam gdzie krzyczał kompilator - nowsza wersja toolchaina.Statystyki: Napisane przez m_wojcik74 — 10 gru 2018, o 16:59
