摘要
随着彩屏显示,触屏技术的日益成熟,原工控设备行业逐渐引入彩屏触屏控制技术。本文介绍了基于NXP的ARM7系列芯片集成LCD控制实现工业控制领域的人机交互系统的设计与实现。对比原通用PC平台或传统ARM9平台,本项目有显著的成本和性能优势,并实现汉字兼容输入输出,并且可选各种中文字体,满足本土应用的需要。
With the color display,touch screen technology matures,the original industrial equipment industry moves to color touch screen control technology.This paper introduces the NXP's ARM7 family-based integrated LCD control chip to achieve human-computer interaction field of industrial control system design and implementation.Compared to the original or conventional ARM9 gener al-purpose PC platform,this project has significant cost and performance advantages,character-compatible inputs and outputs are achieved,and optional for all types of Chinese characters,to meet the needs of local applications.
