毕业设计—嵌入式计算器

摘   要
嵌入式计算器用途广泛，可以应用到PDA、手机等多个领域。目前，嵌入式计算器已被广大用户所使用，给越来越多的人提供了便利，它做用到的嵌入式技术更是正逐渐的走向成熟。嵌入式技术是嵌入式计算机技术的简称，由于它有着体积小，功耗低，携带方便等特点，因此已应用到我们生产生活的很多领域。
本课题是在嵌入式操作系统Windows CE下，实现对嵌入式计算器的设计。主要的功能是通过触摸屏实现计算器的基本功能，实现输入数据和显示计算结果等操作。
本文首先介绍了课题的研究意义，并且对本次设计所采用的嵌入式系统做了详细的介绍，包括嵌入式系统的特点，现状和发展前景。其次，介绍了本次设计的硬件模块。其中重点介绍了ARM920T为内核的S3C2410处理器的优点以及管脚功能。
本文重点介绍了嵌入式计算器软件的设计。结合软件流程图，系统的介绍了在Windows CE平台上的应用程序，详细的说明了软件的功能，并且对从界面设计到编写程序的整个过程进行了详细的说明。
本设计最终实现了在嵌入式操作系统Windows CE中的嵌入式计算器的功能。通过调试，成功实现了基本运算以及科学计算的功能。

关键词：嵌入式系统；计算器；Windows CE

Abstract
Embedded calculator has a wide range of uses, it can be applied to PDA, cell phone and other fields. At present, the embedded calculator has been used by the majority of users, and provides convenience for more and more people, embedded technology whitch it used is being gradually more and more mature. Embedded technology is referred to as embedded computer technology, since it has the specialty of small size, low power consumption, easy to carry, it has been applied to our production in many areas of life.
This topic is in the embedded Windows CE operating system, to realize the design of embedded calculator. Their main function is to achieve the basic functions of a calculator through the touch screen and to enter data and display the results.
This text first introduces the significance of the study subjects, and makes a detailed introduction of the embedded system whitch is uesed in the design, Including the characteristics of embedded systems, the status and development prospects. Secondly, the paper introduces the hardware design, introduces the design of the hardware module, which focuses on the ARM920T processor whitch is looked as the core advantage of the S3C2410 and the pin functions.
This text focuses on the design of embedded computer software. Combining the software flow chart, the topic introduced the applications in the Windows CE platform. It introduced the function of the software, and made a detailed description of the the entire process from interface design to writing program.
The design realized the function of the embedded caculator whitch is in the Windows CE embedded operating system. Through the debugging, the calculator realized the basic computing functions, as well as scientific computing.

Key words: Embedded system; Calculator; Windows CE
