文档介绍:摘要
微电子技术的发展和工业测量的需求,使便携式设备有着很好的发展前景。便携式设备体积小,单电源供电,多种电压输出的特点,使其模块的设计有其特殊性。通过对便携式仪表典型硬件结构的分析,总结了各功能模块的需求,提出了便携式仪表处理的一般方法。
大部分的数字便携式设备是基于单片机系统开发的,在单片机系统中,除了需要特定的功能算法和传感器等器件外,还需要输入,输出装置,在便携式设备中,输入装置一般是键盘,而输出装置一般是液晶显示模块。主要完成工作有实现按键内容的液晶显示,实现按键功能的液晶显示,实现便携式设备的结果输出。
新一代的便携式设备将是一个开放的系统概念,它不再是功能单一的和固定的结构。尽管我们不知道未来便携式设备将最终发展到何种程度,但我们很清楚,随着计算机网络技术,通讯技术的进步及应用的不断拓展,便携式设备正在向智能化,组合化,网络化的方向发展,适应性越来越强,功能也越来越丰富。新一代便携式设备将在各行各业中得到越来越广泛的应用。本文将主要讨论基于SED1520的液晶显示屏的实现。

Abstract
Microelectronics technology development and industrial measurement requirements to enable a portable device has a very good development devices are small, single power supply, multi-voltage output characteristics of the design of its module has its own instrument on the analysis of a typical hardware structure, summed up the needs of the various functional modules, portable instruments proposed general methods to digital portable device is based on the SCM system development, in the SCM system, in addition to specific features such as algorithms and sensor devices, but also need to input and output devices, portable devices, usually keyboard input devices, and outputLCD module is generally plete the work to achieve the main contents of the liquid crystal display, liquid crystal display to achieve key functions, the results of the portable device generation of portable devices will be an open system concept, it is no longer a single function and a fixed we do not know Weilai portable devices will eventually develop to the extent but we are very clear, as work technology, communication technology and Ying Yong continue to expand, to the intelligent portable device Zhengzai, modularized, networked Fang Xiangdevelopment, adaptability growing, increasingly rich in generation of portable devices will be increasingly in all walks of life in a wide range of article w
