At the beginning, I was not sure what kind of OLED was used, so I tried using UG2864HSWEG01, and the result went further and further on the wrong path. Later when the SSD1306 universal driver was selected for the last attempt, it would then display normally. So I chose the wrong driver from the beginning, which is a very serious low-level error. This is really a joke, so before any attempt, you must figure out what device you are using. This is the lesson I learned through this attempt. BR NiiJyeni
