Keywords:graphical interface  PIC MCU  Microchip graphics library  display device controllers 

The proliferation of graphical interfaces in ordinary devices is becoming noticeable. As we go along our daily activities, more and more products we encounter have some form of graphical interface. As this feature becomes a de facto standard, the need to manufacture these devices at a lower cost becomes apparent. PIC MCU, with their reputation for low risk product development, lower total system cost solution and faster time to market, makes this realisable. The Microchip graphics library makes it very easy to integrate graphical features in an application.

The Microchip Graphics Library was created to cover a broad range of display device controllers. Targeted for use with the PIC MCU, it offers an Application Programming Interface that performs rendering of primitive graphics objects as well as advanced widget-like objects. The library also facilitates easy integration of input devices through a messaging interface. Applications created using the library will also find a simple and straightforward process to change display devices if the need arises. The layered architectural design of the library makes all of these possible.

This application note details how a 16bit MCU with a graphical library is used to drive a QVGA display supporting 16bit colours.
