NanoEngine16 is simple graphics engine, that implements double buffering work for the systems with very low resources. That is, memory buffer for SSD1351 oled display needs at least 128x128x2 bytes (32768 bytes), and this is inacceptable for microcontrollers like atmega328p (it has only 2KiB of RAM). So, to workaround issue with low resources, NanoEngine16 uses small tile buffer (NE_TILE_SIZE x NE_TILE_SIZE) and updates only part of oled screen at once. It makes system slow, but it is possible to run NanoEngine16 on simple controllers. If tile size is 16x16, then 128x128 oled display is devided into 64 tiles:
[0,0] [1,0] [2,0] [3,0] [4,0] [5,0] [6,0] [7,0]
[0,1] [1,1] [2,1] [3,1] [4,1] [5,1] [6,1] [7,1]
etc.
In your application you can choose, if you want to refresh whole screen (refresh()), or you need to refresh only part of oled display.
