Description:
|
|
Update a sub area of the display, given by tile position, width and height.
|
|
The arguments are "tile" coordinates. Any u8g2 rotation is ignored.
|
|
This procedure only checks whether full buffer mode is active.
|
|
There is no error checking for the arguments: It is the responsibility of the
|
|
user to ensure, that the provided arguments are correct.
|
|
|
|
Limitations:
|
|
- Only available in full buffer mode (will not do anything in page mode)
|
|
- Tile positions and sizes (pixel position divided by 8)
|
|
- Any display rotation/mirror is ignored
|
|
- Only works with displays, which support U8x8 API
|
|
- Will not send the e-paper refresh message (will probably not work with e-paper devices)
