LCD显示模块并行接口驱动程序设计

The drive program design of LCD display module parallel Interface

通过对市场上多种LCD驱动器分析后,列举一款典型驱动器用法来研究LCD并行接口驱动程序通用设计方法,通过对LCD显示字体、图像和图形的特点编写出置点、画线、显示字体和清理屏幕等函数(本文给出部分程序清单)。如果对接口函数改写,这些程序可以应用于其他LCD驱动器中。在实际应用中,通过置点、画线、显示字体和清理屏幕这四个函数就可以做出一个简单的操作界面和显示界面。

According to the analysis of many LCD drivers in the market and the example of a typical driver usage, It is studied that the general design of LCD drive program of parallel interface. And the functions of point-placing, line-draw ing, font-displaying and screen cleaning are compiled through the research of the characters of displaying font, picture and graph （Part of the programs are listed）. If rewrite the interface function properly, the program can be compatible with other LCD drivers. The functions of point-placing, line-drawing, font-displaying and screen-cleaning can he adopted in the completion of a simple operation panel and display panel.
