Ich habe wenig Erfahrung damit Display mit ein Arduino anzusteuern und keine Erfahrung mit OLED Displays.
Meine Vorgehensweise war, den Chipnamen des Displays: 'SSD1309' in den Arduino libiry Bibliotheken zu suchen und in der Passenden Bibliothek das 'Hello Word' oder ein 'test01' Programm zu starten und zum laufen zu bringen. Der Display ist von Werk auf das SPI Protikoll eingestellt und dies will ich auch verwenden.
Ich benutze die U8g2 Bibliothek und habe aus der Beispielsammlung das Programm: "HelloWorld.ino" gestartet. In dem Programm habe ich den Kommentar in Zeile 106 Entfernt, sodass ich mein Grafikchip einbinden kann: "U8GLIB_SSD1309_128X64 u8g(13, 11, 10, 9);"
Meine Pinbelegung ist wie folgt:
Display zu Arduino Uno
CS --> Pin 10
DC --> Pin 9
RES --> Pin 8
SDA --> Pin 11
SCL --> Pin 13
VCC --> 5V
GND --> GND
Trotzdem bleibt der Display schwarz. Ist das Normal das ein OLED schwarz bleibt, auch wenn man ihn mit Spannung versorgt?
Ich habe die Verbindungskabel und die Steckverbindung überprüft, die Leiten alle.
Ich habe den Arduino ausgewechselt und es kommt zum selben Ergebnis.

Bitte etschuldigt mein unsauberes ausdrücken. Ich nutze SPI weil ich dafür den Monitor nicht Modifizieren muss und weil mich das eine Kabel mehr nicht stört.
ich kenne mich mit den Bibliotheken nicht aus und weiß nicht, welche gerade unterstützt wird und welche nicht.

U8g2lib Example Overview:
Frame Buffer Examples: clearBuffer/sendBuffer. Fast, but may not work with all Arduino boards because of RAM consumption
Page Buffer Examples: firstPage/nextPage. Less RAM usage, should work with all Arduino boards.

ich habe die Bibliothek nun geändert. Danke für den Hinweis. Jetzt geht es.
Wie und Wo kann ich einsehen, ob die Bibliothek die ich gerade verwenden will noch aktuell ist?
