Hello,
For my projects I usually use 128x64px OLED screens. So far no problem with the U8glib library for a basic Nano board. It turns out that I have to use a Nano Every board. The U8glib library is incompatible just like the Adafruit GFX and SSD1306 libraries.
Can someone quote me a functional library for an OLED 128x64px screen and that is compatible with a Nano Every ?
Adafruit_SSD1306 works on EVERY
U8g2lib works on EVERY
Update your libraries via the IDE Library Manager
Yes, it is important to report any library that "does not work" with EVERY. A reader might offer a Pull Request to the library Author on GitHub. Or simply raise an Issue.
The Adafruit code was fixed within a few days after the EVERY came on the Market.
David.
