MarlinFirmware/Marlin/status_screen_DOGM.h
Scott Lahteine 1c95c13224 Lightweight status screen for ST7920 
- This status screen uses the ST7920 character generator to greatly reduce SPI traffic and MCU load when updating the status screen.

- Has been tested with the RepRapDiscount Full Graphics Smart Controller but should work with any LCD that uses an ST7920 or fully compatible controller.
