Introduction 

emWin is a graphic library with graphical user interface (GUI) designed to provide an efficient, 
processor  and  display  controller-independent  GUI  for  any  application  that  operates  with  a 
graphical display. 

Nuvoton  provides  emWin  GUI  library  for  free  with  the  M480  series  microcontroller  (MCU) 
supporting  up  to  320x240  (16  bpp)  resolution.  The  emWin  platform  can  be  implemented  on 
HMI for industrial, machines, appliances, etc.
