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? https://reprap.org/forum/read.php?13,894920,894920#msg-894920 Sat, 11 Apr 2026 06:50:11 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?13,894920,894920#msg-894920 https://reprap.org/forum/read.php?13,894920,894920#msg-894920 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.
