摘要

采用了一种DSP控制LCD模块的显示方案

并对系统的硬件和软件进行了分析。该方案关键在于采用通用I/O口对读写时序进行模拟

利用C语言具体的实现方法以及LCD模块丰富的显示功能

实现了DSP与LCD显示模块的良好接口

并在实际工作场合得到了应用。测试结果表明

该显示系统工作稳定、显示效果较好、刷新速度快

能够达到预期显示目标。

Abstract

A display program of LCD display module controlled by DSP has been adopted

and the systems hardware and software are analyzed.This display program lies in timing simulation of writing and reading by using general I/O port. Using specific implementation methods of C language

and rich display of LCD module

a better interface between DSP and LCD display module is realized

and has been applied in the actual workplace. Test shows that the display system is stable

and has better display quality and faster refresh rate

can achieve the desired objectives.
