I still have a 12864 display from an Anycubic Mega Zero, but this only has one ISP 10-pin connector. If I understand the connection diagram correctly, this should still work because the display does not have an SD card slot. When I connect the display, the backlight works but nothing else. Do I have to reconfigure something here in Marlin? I once entered the settings for the RepRap display, but without success.
Thanks for your help.
