摘要

采用TMS320LF2407 DSP 和1/4VGA液晶显示模块设计了一种便携式检测仪器的显示系统。给出了DSP 与液晶显示模块之间的硬件接口设计方案

基于C语言编写了控制程序

解决了DSP 与液晶显示模块之间的时序匹配问题。该程序具有较好的移植性

可方便地用于其他由DSP 和LCD组成的显示系统中。

Abstract

The display system for a portable detecting instrument was designed based on TMS320LF2407 DSP and 1/4VGA LCM . The design scheme of the hardware interface between DSP and LCM was presented

and the control software was programmed using C language which resolved the timing match problem between DSP and LCM. With good implementation

the control program can be used easily in other display system consisted by DSP and LCM.
