Oled Kein Bild nur komische Streifen

peter1941 · November 16, 2025, 10:47pm

Versuche schon seit 2 Tagen das teil zum laufen zu kriegen..

1OLED 1.3 von AZ-Deliv. im Test Super nur die Treiber beisen sich mit dem Programm.

unten ist das Bild (Test) in Ordnung….

Installierter Treiber u8g2

Du hast mein volles Mitgefühl!

Rintin · November 17, 2025, 4:50am

Welcher Arduino?
Schaltplan?
Code?
Fehlermeldungen?
Was macht es?
Was soll es machen?

Erklär mal ein wenig genauer was du da machst.

HotSystems · November 17, 2025, 8:40am

Warte nur kurz, bis ein Hellseher dein Problem löst.

peter1941 · November 17, 2025, 10:07am

keine Bange…war Schon Spät gestern….bevor noch was Passiert…

also….

Wetter Station mit einem BME280 und einem OLEd 1.3

Ich wollte nur sicher gehen das das OLED noch in Ordnung ist…

sind soweit alle in ordnung, habe bis eben einige Tests mit dem BME über seriellen Monitor

der ist auch in Ordnung.

ich hatte laut meinem Arduino Almanach….mir die Adafruit SSD1306 installiert….

nur diese erzeugt immer noch mein komisches Bild…bei Gleichzeitiger Anzeige am Ser. Monitor

sensor Arbeitet OLED nicht (nicht Richtig!)

mein Händler AZ Delivery hat aber einen Ganz Andere Treiber Quelle….U8g2

dort wird aber mein OLED komischer weise aber Richtig dargestellt…..?

was ist zwischen den Beiden Treibern Anderst ?

mit dieser Zeile muss es irgendwie zusammen hängen?

Du machst Sachen Der Test mit dem OLED war wahrscheinlich mit U8G2 gemacht, im deinem Sketsch willst du Adafruit nutzen, jedoch mit flachem Treiber.
Die 1,3" Displays haben meistens SH1106.
werfe den ganzen Adafruit kram raus und nutzt den U8G2.

fony · November 17, 2025, 11:46am

Ich bau dir was.
Kompiliert sauber, nicht getestet da ich keinen 1,3" Display frei habe.

soweit so gut…..es hat die Größe eines…0.91 zoll Displays und das Flackern kommt warscheinlich davon das das display kleiner sein müsste…

ich das 0.91er dürfte die besagten Pixel haben….128 x 32 Pixel kompatibe

das müsste ich nur noch anpassen das wärs?

fony · November 17, 2025, 1:12pm

Also was für Display hast du?

fony · November 17, 2025, 1:15pm

  u8x8.clearDisplay();

mein Fehler das macht das Flackern, lesche oder kommentiere das

ein 1.3 OLED von Az-delivery 128X64 pixel.

fony · November 17, 2025, 1:26pm

Für BME280 nutze die

peter1941 · November 17, 2025, 1:26pm

das Funktioniert doch schon wie es soll..

fony · November 17, 2025, 1:35pm

Ja nur die Adafruit verbraucht viel Speicher.

peter1941 · November 17, 2025, 1:37pm

sonnst alles wie bei Adafruit?

der Schmale Sichbare Bildschirm bleibt?

dachte er wäre Größer? (Breiter)

er spart so Strom?

fony · November 17, 2025, 4:17pm

Nein, die Abfrage ist etwas anders.

Verstehe nicht.
Die Position stellt man mit

u8x8.setCursor(x, y)

x ist die Horizontale Pos.
y ist Vertikale Pos.

Nein, um Stromsparren brauch man zB. ein ATtiny1614

HotSystems · November 17, 2025, 4:35pm

Hast du deswegen den Sensor und das Oled an 3,3Volt angeschlossen?
Warum nicht an 5Volt ?

peter1941 · November 17, 2025, 5:33pm

ne alles in Ordnung alles auf 5V

ich kenne diesen Treibe noch nicht.
