E-Paper displays have 2 operating modes: full update and partial update.
While full update delivers a clean and sharp picture it has the disadvantage of taking several seconds for the screen update and shows severe flickering during update.
Partial update is quite fast (300 ms) with no flickering but there is the possibility that erased content is still slightly visible.
To "whiten" the display it is therefore useful to perform a full update in regular intervals (e.g each hour).
To refresh the display it is therefore useful to perform a full update in regular intervals (e.g each hour).
Compilation \#defines => `USE_SPI`, `USE_DISPLAY`, `USE_DISPLAY_EPAPER29`, or `USE_DISPLAY_EPAPER42`
Compilation directives: `#define USE_SPI`, `#define USE_DISPLAY`, `#define USE_DISPLAY_EPAPER29`, or `#define USE_DISPLAY_EPAPER42`
Remark: the 4.2 epaper requires about 15k of RAM. Therefore it only works with Core 2.42 and above

I<sup>2</sup>C displays are connected in the usual manner and defined via the GPIO component selection.
The I<sup>2</sup>C address must be specified using `DisplayAddress XX`, e.g., `60`. The model must be spedified with `DisplayModel`, e.g., `2` for SSD1306. To permanently turn the display on set `DisplayDimmer 100`. Display rotation can be permanently set using `DisplayRotate X` (x = `0..3`).
