|

*
|

* This alternative status screen makes use of the built-in character

* 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.
