Hello,
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.
Hi, have not found this LCD wiring , but seems it is not compatible. https://github.com/markniu/PandaPi/wiki/How-to-wire#2-connect-to-lcd12864
In marlin configuration.h you need to turn off the dgus display that is set by default. Look for the following lines and add // as shown. You will have to compile again. See if that fixes the display. If it doesn't I would just buy a standard Reprap discount graphic smart controller (cheap as hell on ebay). I tried to figure out a similar display from a MKS robin lite setup and waisted way too much time trying.
