what did you do exactly? I did this:
Click “This PC” → Documents → Arduino → libraries → U8g2 → src → U8x8lib.cpp → Sliding to 1334 line → delete or disable this line → save the file.
which I took directly from the wiki about oled, but it still doesn’t work. I deleted the line; I also tried the solution of adding Oled.setBusClock(100000), but also didn’t work.
