I have spent a long time trying to get SD card support working on a Full Graphic Display and RAMPS. I have tried 2 Megas, 2 RAMPS, 2 displays and 5 SD cards (All formatted multiple times). Neither of them seem to work!
I enabled SDSupport in Marlin and selected the right controller so it does work normally (the dispaly at least). I have also tried using the SD card library example to read data off the SD card, or at least to detect it. Marlin says the SD card was inserted but the menu says No SD Card. I have tried adding a delay to the code, and chaning a bunch of the speed settings and init rates. I've tried two different sets of cables, different 'smart adapters' and manually hooking up the pins to an Arduino Mega and an Uno.
I am not sure if I have been extremely unlucky and had two faulty displays, but I can't see what else I can try to check I haven't made a silly mistake.
Any suggestions are welcome :)
Thanks in advance!
