 * Smart LCD adapter
 *
 * The Smart LCD adapter can be used for the two 10 pin LCD controllers such as
 * REPRAP_DISCOUNT_SMART_CONTROLLER.  It can't be used for controllers that use
 * DOGLCD_A0, DOGLCD_CS, LCD_PINS_D5, LCD_PINS_D6 or LCD_PINS_D7. A custom cable
 * is needed to pick up 5V for the EXP1 connection.
 *
 * SD card on the LCD uses the same SPI signals as the LCD. This results in garbage/lines
 * on the LCD display during accesses of the SD card. The menus/code has been arranged so
 * that the garbage/lines are erased immediately after the SD card accesses are completed.
