6、通過c語言編譯，完成實(shí)時(shí)時(shí)鐘（rtc）的顯示。第二節(jié) 程序和芯片初始化 程序中包括：lcd的初始化：中斷向量的初始化：rtc的初始化： 第三節(jié) 構(gòu)建功能模塊lcd顯示的時(shí)鐘界面包括：靜止不動(dòng)的圓形鐘面和一直在走動(dòng)的時(shí)鐘指針。所以需要構(gòu)建兩個(gè)重要的函數(shù)實(shí)現(xiàn)畫圓和畫直線。以下為畫圓函數(shù)：該算法是通過x變量的自增，補(bǔ)償1 修正正方形控制y變量自減，找到距中心恒定距離的點(diǎn)，其中rs=45，x自0加1增至45。和原點(diǎn)坐標(biāo)運(yùn)算，可以在第一象限找到一點(diǎn)，再通過折疊對稱找到其他象限的三個(gè)點(diǎn)，通過畫點(diǎn)函數(shù)描繪出。再畫他的45度鏡像就好了。畫線函數(shù)：void line(unsigned int x1,unsign

7、ed int y1,unsigned int x2,unsigned int y2,unsigned char draw)以中心的坐標(biāo)為起點(diǎn)，使用while函數(shù)與指針最外圈的點(diǎn)比較，不斷延長直至相等，所以事先計(jì)算出時(shí)針，分針和秒針三個(gè)同心圓最外圈點(diǎn)的坐標(biāo)，以便帶入函數(shù)。也同圓類似，要考慮不同象限點(diǎn)的情況，根據(jù)不同的位置帶參數(shù)到畫點(diǎn)函數(shù)中描繪。 第四節(jié) 實(shí)現(xiàn)信息的傳遞畫點(diǎn)函數(shù)：數(shù)據(jù)傳遞函數(shù)：與通用可編程輸入輸出口（general programable input output）相連，把計(jì)算的數(shù)據(jù)傳遞給lcd顯示。第二章 實(shí)驗(yàn)結(jié)果討論第一節(jié) 軟件的編譯，連接和運(yùn)行 構(gòu)建完整的程序：添加頭文件，中

8、斷處理匯編程序段，初始化函數(shù)和主函數(shù)：編譯器提示：成功生成所需hex文件，將得到的hex文件導(dǎo)入仿真芯片中，觀察實(shí)時(shí)時(shí)鐘。第三章 結(jié) 論綜合效果圖：以上為protues部分設(shè)計(jì)的，ads程序見附錄。心得體會(huì) 回顧起此次課程設(shè)計(jì)，至今我仍感慨頗多，從理論到實(shí)踐，我學(xué)到很多很多的東西，不僅鞏固了以前所學(xué)過的知識，而且學(xué)到了很多在書本上所沒有學(xué)到過的內(nèi)容。通過這次課程設(shè)計(jì)使我懂得了理論與實(shí)際相結(jié)合是很重要的，只有理論知識是遠(yuǎn)遠(yuǎn)不夠的，只有把所學(xué)的理論知識與實(shí)踐相結(jié)合起來，從理論中得出結(jié)論，才是真正的知識，才能提高自己的實(shí)際動(dòng)手能力和獨(dú)立思考的能力。在設(shè)計(jì)的過程遇到了各種各樣的問題，同時(shí)在設(shè)計(jì)的過程中

9、發(fā)現(xiàn)了自己的不足之處，對以前所學(xué)過的知識理解得不夠深刻，掌握得不夠牢固，通過這次課程設(shè)計(jì)，把以前所學(xué)過的知識重新溫故，鞏固了所學(xué)的知識。參考文獻(xiàn)1 謝自美，電子線路設(shè)計(jì)、實(shí)驗(yàn)、測試，華中理工大學(xué)出版社，2003。2 宋春榮，通用集成電路速查手冊，山東科學(xué)技術(shù)出版社，1995。3 arnold berger，嵌入式系統(tǒng)設(shè)計(jì)，呂駿 譯， 北京：電子工業(yè)出版社, 20024 桑楠. 嵌入式系統(tǒng)原理及應(yīng)用開發(fā)技術(shù)，北京：北京航空航天大學(xué)出版社, 2002 附 錄1、 一、源程序：#include .incconfig.h#definestacksize256#define x_line 160#def
