- 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.pull/1/head

/**
|

* Implementation of a Status Screen for the RepRapDiscount |
|||
* Full Graphics Smart Controller using native ST7920 commands |
|||
* instead of U8Glib. |
|||
* |
|||
* This alternative Status Screen makes use of the built-in character |
|||
* generation capabilities of the ST7920 to update the Status Screen |
|||
* with less SPI traffic and CPU use. In particular: |
|||
* |
|||
* - The fan and bed animations are handled using custom characters |
|||
* that are stored in CGRAM. This allows for the animation to be |
|||
* updated by writing a single character to the text-buffer (DDRAM). |
|||
* |
|||
* - All the information in the Status Screen is text that is written |
|||
* to DDRAM, so the work of generating the bitmaps is offloaded to |
|||
* the ST7920 rather than being render by U8Glib on the MCU. |
|||
* |
|||
* - The graphics buffer (GDRAM) is only used for static graphics |
|||
* elements (nozzle and feedrate bitmaps) and for the progress |
|||
* bar, so updates are sporadic. |
