軟硬件 DS1302 與 CPU 的連接需要三條線,即 SCLK(7)、 I/O(6)、 RST(5)。另外,還可以在上面的電路中加入DS18B20,同時顯示實時溫度。 實現過程:由串行的時鐘芯片 DS1302,送給單片機,單片機處理后輸出。 程序流程框圖 商丘工學院畢業(yè)論 文 13 基于單片機的萬年歷設計 14 商丘工學院畢業(yè)論 文 15 圖 C 時間調整程序流程圖 基于單片機的萬年歷設計 16 商丘工學院畢業(yè)論 文 17 第四章 實驗測試部分 測試結果分析 ( 1).在測試中遇到發(fā)光二極管、 LED 數碼管為不顯示時 ,首先使用試測儀對電路進行測試 ,觀察是否存在漏焊 ,虛焊 ,或者元件損壞 . ( 2). LED 數碼管顯示不正常,還有亮度不夠,首先使用試測儀對電路進行測試 ,觀察電路是否存在短路現象。 DS1302 與 RAM 相關的寄存器分為兩類 :一類是單個 RAM 單元,共 31 個,每個單元組態(tài)為一個 8 位的字節(jié),其命令控制字為 C0H~ FDH,其中奇數為讀操作,偶數為寫操作;再一類為突發(fā)方式下的 RAM 寄存器,在此方式下可一次性讀、寫所有的 RAM 的 31 個字節(jié)。如果斷電時間較短 (幾小時或幾天 )時,就可以用漏電較小的普通電解電容器代替。 測試結論 經過多次的反復測試與分析 ,可以對電路的原理及功能更加熟悉 ,同時提高了設計能力與及對電路的 分析能力 .同時在軟件的編程方面得到更到的提高 ,對編程能力得到加強 .同時對所學的知識得到很大的提高與鞏固 基于單片機的萬年歷設計 18 第五章 結論 在整個設計過程中,發(fā)揮團隊精神,分工合作,充分發(fā)揮人的主觀能動性,自主學習,學到了許多沒學到的知識,完成了對萬年歷的設計,達到了預期的目的。程序編寫中,由于思路不清晰,開始時遇到了很多的問題,經過靜下心來思考,理清了思路,終于能夠完成它。 商丘工學院畢業(yè)論 文 19 參考文獻 1劉勇 編 數字電路 電子工業(yè)出版社 2021 2陳正振 編 電子電路設計與制作 廣西交通職業(yè)技術學院信息工程系 2021 3楊子文 編 單片機原理及應用 西安電子科技大學出版社 2021 4王法能 編 單片機原理及應用 科學出版社 2021 5曹琳琳.單片機原理及接口技術【 M】.北京:國防科技大學出版社, 2021 年. 6 許惠民.單片微型計算機原理、接口及應用 fM】. 北京:北京郵電大學出版社, 2021 年. 7康華光.電子技術基礎【 M】.北京:高等教育出版社, 2021 年. g an employment tribunal clai Employment tribunals sort out disagreements between employers and employees.

Starting at the ground, conditions have to be very calm winds less than 2 mph, with no precipitation or humidity and limited cloud cover. The balloon, with capsule attached, will move through the lower level of the atmosphere (the troposphere) where our daytoday weather lives. It will climb higher than the tip of Mount Everest ( miles/ kilometers), drifting even higher than the cruising altitude of mercial airliners ( miles/ kilometers) and into the stratosphere. As he crosses the boundary layer (called the tropopause),e can expect a lot of turbulence. The supersonic descent could happen as early as Sunda.
