摘　　要：介绍了S3C44B0X内置LCD控制器的原理与使用,并给出了该控制器与320×240的LCD硬件接口方法,在此基础上,详细论述了如何初始化S3C44B0X内置的LCD控制器,包括配置LCD控制端口,申请显示缓冲区,配置LCD控制寄存器等。在介绍了LCD上任意坐标画点程序的基础上,给出了LCD实现图形显示和字符显示的方法,并经实验验证此方法的正确性。This paper introduces the principle and application of LCD controller embedded in S3C44b0X. it also gives the hardware interface method for connecting the controller to the 320×240 LCD. It puts emphasis on how to initiate a LCD controller embedded in S3C44b0X, including configuring the controlling port and controlling register of LCD, as well as applying for the display buffer. On the basis of a program to draw a point in an arbitrary area on a LCD screen, it introduces a method for displaying both graphics and characters on the LCD screen. The experimental result shows its correctness.
