Hallo an alle,
erstmal danke für eure vorherige Hilfe die mich super weitergebracht hat. Deshalb hoffe ich auf erneute Unterstützung. Ich möchte gerne ein simples SH1106 OLED Display mit dem Pico zum laufen bekommen. Das einzigste was ich bisher geschafft hatte war, das ich das Display mit deiner "blauen Monochromen Farbe" zum leuchten gebracht habe und das Display willkürlich irgendwelche Pixel anzeigte. Folgenden Code habe ich bereits:
als sh1106.py auf dem Pico (nicht im /lib/ Ordner, sondern außerhalb im Hauptverzeichnis:
In dieser Bibliothek sind natürlich Beispiel Codeschnipsel enthalten, die ich auch nutze. Pin- Belegung liegt bei mir auf 16 und 17 für SDA, SCL. Folgenden Code habe ich bereits und "Thonny" sagt keinen Fehler:
Desweiteren hat von euch bestimmt noch jemand einen Tip, wie ich diese beiden Module zum laufen bekommen, denn im Netz findet sich fast nichts, und wenn dann nur sehr sperrige Infos oder gar nur für Arduino/Raspberry Pi dazu:
