Hello.
I'm trying to get to work a graphic oled 2.42 inch display with my printer running Marlin 2.1.2.2 with Arduino Mega + Ramps 1.4.
The display has I2C and SPI capabilities, although the default is SPI.
I tried first with an Arduino board and after some trial and error I was able to make it work.
Besides the regular SPI signals (MISO, CLK & CS) needs two more signals Reset and DC.
As far as I could find, most configurations handle in the best case the CD signal but I was not been able to drive the reset properly. I tried most of the configurations available in Configuration.h but I got nothing in the display at all.
Any pointers?
