畢業(yè)設(shè)計—嵌入式計算器

摘   要
嵌入式計算器用途廣泛，可以應(yīng)用到PDA、手機等多個領(lǐng)域。目前，嵌入式計算器已被廣大用戶所使用，給越來越多的人提供了便利，它做用到的嵌入式技術(shù)更是正逐漸的走向成熟。嵌入式技術(shù)是嵌入式計算機技術(shù)的簡稱，由于它有著體積小，功耗低，攜帶方便等特點，因此已應(yīng)用到我們生產(chǎn)生活的很多領(lǐng)域。
本課題是在嵌入式操作系統(tǒng)Windows CE下，實現(xiàn)對嵌入式計算器的設(shè)計。主要的功能是通過觸摸屏實現(xiàn)計算器的基本功能，實現(xiàn)輸入數(shù)據(jù)和顯示計算結(jié)果等操作。
本文首先介紹了課題的研究意義，并且對本次設(shè)計所采用的嵌入式系統(tǒng)做了詳細的介紹，包括嵌入式系統(tǒng)的特點，現(xiàn)狀和發(fā)展前景。其次，介紹了本次設(shè)計的硬件模塊。其中重點介紹了ARM920T為內(nèi)核的S3C2410處理器的優(yōu)點以及管腳功能。
本文重點介紹了嵌入式計算器軟件的設(shè)計。結(jié)合軟件流程圖，系統(tǒng)的介紹了在Windows CE平臺上的應(yīng)用程序，詳細的說明了軟件的功能，并且對從界面設(shè)計到編寫程序的整個過程進行了詳細的說明。
本設(shè)計最終實現(xiàn)了在嵌入式操作系統(tǒng)Windows CE中的嵌入式計算器的功能。通過調(diào)試，成功實現(xiàn)了基本運算以及科學計算的功能。

關(guān)鍵詞：嵌入式系統(tǒng)；計算器；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
