- *
- * 2. Create TWO buffer with some rows:
- * LittlevGL 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 LittlevGL 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. Create TWO screen-sized buffer:
- * Similar to 2) but the buffer have to be screen sized. When LittlevGL is ready it will give the
