The display is marked as KXM12864M-3 which might have an ST7920 controller. It looks like the U8g2 library might work with it.

The links that I sent to you in your other thread did not help?

You did not even look at them.

I am out.

I think that Marlin uses a 256-byte page buffer so one of the ones with "2" in the middle. The interface is SPI so you need to choose hardware SPI ("_HW_SPI") or software SPI ("_SW_SPI"). You are NOT using the 8-bit parallel interfaces of the ancient 8080 or 6800 processors.
