Hello Rodrigo, unfortunately I don’t think the SDD1306 library comes with a scroll function to make it easier to implement… I also never did it, so I don’t have any code examples on that subject.

I’m use this library:
https://github.com/squix78/esp8266-oled-ssd1306.git
In exmaples it has : SSD1306DrawingDemo with scroll demo
This library work fine for this ESP32+Oled module:

For module above initialization string is:
SSD1306Wire display(0x3c, 5, 4);

Thanks for letting us know Gayrat! I wasn’t aware that example worked with the ESP8266.
Thanks again for sharing,
Rui

Thanks Gayrat Vlasov …. I did a test with the sample and I had a screen scroll in my heltec. Rui Santos another suggestion for you improve the material….

Thanks for the suggestion and I’m glad it worked. I’ll try to add a Unit about the OLED in the future!
