| 摘 要： | 对基于DSP的图形液晶显示的研究做了一定的探讨,分析了基于DSP的图形液晶显示器的硬件电路以及程序设计。利用CCS开发环境,设计出一个基于DSP的图形液晶显示屏,能达到与程序运行相符合的显示结果。即通过更改、调试程序,最终实现静态显示、动态垂直向上向下滚屏显示、左右半屏从右至左逐字显示、全屏从左至右逐字显示汉字的功能,其他功能的实现有待进一步的研究。

| Abstract: | The study of graphic LCD (Liquid Crystal Display) based on DSP is discussed, and the hardware and procedure design are analyzed. Graphic LCD based on DSP is designed using CCS exploitation environment, the display results can be accordant with the procedure course. Through modifying and debugging the procedure of Figure LCD, it achieves the function of displaying statically, scrolling dynamically and vertically from top and from bottom, displaying literally from right to left in half screen, displaying from left to right in whole screen. Further studies will be proceeded to achieve other functions of Figure LCD. |
