智能電子鐘LCD應(yīng)用電子專業(yè)綜合課程設(shè)計報告書

1、專業(yè)綜合課程設(shè)計報告題目：智能電子鐘（LCD）題目智能電子鐘（LCD）一、 設(shè)計要求：制作一個LCD顯示的智能電子鐘：(1) 計時：秒、分、時、日、月、年、星期。(2) 閏年自動判別。(3) 時間、年、月、日、星期交替顯示。(5) 自定任意時刻自動開/關(guān)屏。(6) 計時精度：誤差1秒/月（具有微調(diào)設(shè)置）。二、 方案論證：本實驗可采用并行時鐘芯片（DS12C887）和串行時鐘芯片(DS1302)，DS1302要用戶自己安裝后備電池和串口通訊，要32.768KHz的晶振，而DS12C887自帶后備電池，并口通訊，無需外圍元件，并且DS12C887多了一個字節(jié)來記錄世紀(jì)使用的，處在RAM的32H單元

2、，但是其他的寄存器定義都一樣。由于本實驗用到了STC12C5A60S2直插40P封裝的單片機、nokia5110液晶屏、獨立式按鍵、四路2輸入與門并且都是直插的，而且在實驗室做PCB只能是單層板，為了節(jié)約空間和簡化電路于是就選用了串行時鐘芯片DS1302。三、 理論設(shè)計：用CAD軟件繪制的硬件原理圖電源和程序下載端口，此部分的USB可提供電源和下載端口適用于USB下載端口，DOWN端口適用于四角插針式下載、BAT為備用電源端口。CPU主控部分，此部分采用的是高速51系列的STC12C5A60S2的單片機，該芯片不僅運行速度快穩(wěn)定驅(qū)動能力更大，還為用戶提供了部集成8位/10位可調(diào)分辨率ADC模塊

3、(在此設(shè)計中有用到)，1KB可擦寫EEPROM本設(shè)計中用其設(shè)計成可調(diào)鬧鐘功能存放鬧鐘值。此圖為串行數(shù)據(jù)nokia5110的LCD顯示器模塊，采用可控背光和可控電源有很好的節(jié)能效果。該顯示器能顯示漢字，字符，圖片、并且處理顯示數(shù)據(jù)速度快。此模塊為串行數(shù)據(jù)實時時鐘模塊，此模塊采用的是達拉斯公司生產(chǎn)的DS1302具有閏年補償。此圖為按鍵中斷模塊，在此模塊中每個獨立式按鍵都能申請外部中斷與時處理按鍵按下的值來執(zhí)行用戶的操作。此圖為蜂鳴器模塊此模塊用于鬧鐘鈴聲設(shè)計，和開機提示。此圖為PCB版圖此圖為PCB打印預(yù)覽軟件流程圖開始按鍵檢測，判斷按鍵是否按下yes其他鍵yes按下目錄鍵NO時間處理初始化時鐘功
