摘　　要：在基于LCD控制器T6963C的LCD模块上显示几何图形,需要把计算机图形学中的一些绘图算法移植到显示模块上。通过对T6963C控制器工作原理的分析,采用C51语言编写绘点函数,并根据图形生成算法,给出了在此类模块上绘制常用几何图形的C51函数,最后生成C51函数库。此函数库的设计提高了实际产品研发效率。In order to display geometric graphic on the LCD module based on T6963C LCD controller, it is necessary to transplant the graphic building algorithm in computerized graphics onto display module. Through analyzing the operational principle of T6963C controller, by adopting C51 language to program the plotting point function, and create the algorithm in accordance with the graphic. The C51 functions for creating commonly used graphics on such module are given, and the C51 function library is generated. Thus the efficiency for developing practical prod ucts is enhanced.
