/**
|
||||||
|
* 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.

/* This is an implementation of a status screen for the RepRapDiscount
|
|
||||||
* Full Graphics Smart Controller using native ST7920 commands rather
|
|
||||||
* than using 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.
