LCD / Controller

As of 20 JAN 2019 only the REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER display has been tested with these settings. It can be connected to the SKR using standard cables via the EXP1 and EXP2 ports. Other displays may need a custom cable and/or changes to the pins defined below.

The SD card on the LCD controller uses the same SPI signals as the LCD, resulting in garbage/lines on the LCD display during SD card access. The LCD code mitigates this by redrawing the screen after SD card accesses.
