摘　　要：在嵌入式系统开发设计中,图形用户界面(GUI)是人与计算机进行交互的重要方式,液晶屏作为GUI的重要设备,在智能仪器仪表与高端嵌入式设备中得到广泛运用。文中介绍了基于ARM920T内核的芯片S3C2440内部LCD控制器以及LCD接口电路设计和相应驱动程序开发。并在此基础上移植了一种非常优秀的图形用户接口软件包μC/GUI。经过测试与μC/GUI实例运行,在液晶屏幕上得到了满意的显示效果,证明了液晶显示部分硬件接口、驱动设计以及μC/GUI移植的合理性与稳定性。In process of embedded systems development,graphical user interface（GUI） is an important way for people to interact with the computer.As an important device for GUI,LCD was widely used in intelligent instruments and high-end embedded devices.This article describes the LCD controller in S3C2440 based on ARM920T core,interface circuit of LCD and its corresponding driver development.On this basis,μC/GUI which is a very excellent package of graphical user interface was transplanted in this system.The satisfactory result is attained on LCD screen by running examples of μC/GUI.The interface circuit and driver design for LCD and transplant of μC/GUI are proved reasonable and stable.
