摘要
本系统以高性能ARM9处理器LPC3250为核心，HX88xx为LCOS驱动芯片。HX70xx为LCOS模块，LQ035Q1DG01为LCD模块，建立μC／OS-Ⅱ嵌入式实时操作系统，通过红外控制实现系统在投影仪和LCD之间切换。本文重点阐述了系统主要接口硬件电路的设计和系统软件的实现。实现了寿命长、成本低、可靠性高的便携式微型投影系统的设计。
This system take microcontroller LPC3250 as the core,HX88xx as LCOS driver IC, HX70xx as LCOS module,and LQ035Q1DG01 as LCD module,building μC/OS-Ⅱ Embedded Real-Time Operating System on it,using remote control realize the switch between LCD and projector.This paper focuses on introducing the hardware design of interfaces and system software design,realized a long life,low cost and high reliability design of a portable micro-projection system.
