Bibliothek u8g2 - Programmieren mit Arduino (2024)

Die Biblio­thek u8g2 kann eine Viel­zahl von OLED-Dis­plays ansteuern.

Die ver­schie­de­nen OLEDs müs­sen je nach Typ unter­schied­lich initia­li­siert werden:

0,96 Zoll mit I2C-Ansteue­rung (SSD1306)
U8G2_SSD1306_128X64_NONAME_1_HW_I2C oled(U8G2_R0, U8X8_PIN_NONE);

1,3 Zoll mit I2C-Ansteue­rung (SH1106)
U8G2_SH1106_128X64_NONAME_1_HW_I2C oled(U8G2_R0, U8X8_PIN_NONE);

Hier sol­len die Dis­plays mit den Chip­sät­zen SSD1306 und SH1106 und I2C betrach­tet wer­den.
Die Biblio­thek kennt zwei ver­schie­de­ne Modi den Bild­schirm anzusprechen:

Full screen buf­fer mode schnell, sehr hoher Spei­cher­be­darf mit dem Hin­weis Spei­cher­platz- und Sta­bi­li­täts­pro­ble­me beim UNOR3
