摘要
目前,液晶显示技术在各种低功耗移动通信设备中有着广泛的应用。本文结合为某通信系统设计的控制型手持终端,介绍了其中液晶显示部分的硬件电路接口及软件设计。在硬件设计部分,提出了C8051F120单片机与液晶显示模块TNS-G320200FTDLY-1W接口的电路设计方案。在软件设计部分,首先介绍了端口初始化函数,其次给出了写入数据/指令操作的流程图以及表单显示的过程,最后介绍了实现屏幕操作功能的函数接口。测试表明,设计的液晶显示部分在手持终端中达到了较好的显示效果。
Nowadays, the LCD technology has extensive application in the low-power mobile communication equipment. According to the controller handset designed for a communication system, the paper introduces the hardware circuit interface design and the software design of the LCD part. In the hardware design part, the paper introduces the interface circuit between the C8051F120 single chip microcomputer and the LCD module TNS-G320200FTDLY-1W. In the software design part, the port initialization function is introduced first, and then the flow chart of writing data/ instruction and the process of displaying the list are given. The function interface designed for the screen operation is introduced at last, Test shows that this LCD part has achieved excellent effect in the controller handset.
