White Blank Screen Issue with SSD1306 OLED on STM32

[victor-anthony]

Hi everyone,

White color screen have been a major problem while trying to use an OLED screen with an SSD1306 driver for the first time. Occasionally, the display either freezes, shows random patterns, or remains stuck on a blank white screen. I have checked all my connections and ensured the power supply is stable, but the issue persists.

I’m using it with a STM32, and the code is based on a library like Adafruit SSD1306 . The screen behavior seems to happen more often when I attempt to refresh the display or execute specific parts of my code.

Could this issue be related to the library, the initialization sequence, or a hardware fault? Any advice on debugging or solving this would be highly appreciated!

You did not mention which STM board in specific you are using. The issue may exist in the code or the library or the circuit connection. Here are a few tutorials that may help you with cross-checking.
