* LVGL requires a buffer where it internally draws the widgets.
* Later this buffer will passed to your display driver's `flush_cb` to copy its content to your display.
* The buffer has to be greater than 1 display row
*
* There are 3 buffering configurations:
* 1. Create ONE buffer:
* LVGL will draw the display's content here and writes it to your display
*
* 2. Create TWO buffer:
* LVGL will draw the display's content to a buffer and writes it your display.
* You should use DMA to write the buffer's content to the display.
* It will enable LVGL to draw the next part of the screen to the other buffer while
* the data is being sent form the first buffer. It makes rendering and flushing parallel.
*
* 3. Double buffering
* Set 2 screens sized buffers and set disp_drv.full_refresh = 1.
* This way LVGL will always provide the whole rendered screen in `flush_cb`
* and you only need to change the frame buffer's address.
