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.2.0.x

/**
|
||||
* 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.
