智能電子鐘（LCD）應(yīng)用電子專業(yè)綜合課程設(shè)計(jì)

1、湖北文理學(xué)院物理與電子工程學(xué)院11應(yīng)用電子專業(yè)綜合課程設(shè)計(jì)-智能電子鐘專業(yè)綜合課程設(shè)計(jì)報(bào)告題目：智能電子鐘（lcd）題目智能電子鐘（lcd）一、 設(shè)計(jì)要求：制作一個(gè)lcd顯示的智能電子鐘：(1) 計(jì)時(shí)：秒、分、時(shí)、日、月、年、星期。(2) 閏年自動(dòng)判別。(3) 時(shí)間、年、月、日、星期交替顯示。(5) 自定任意時(shí)刻自動(dòng)開/關(guān)屏。(6) 計(jì)時(shí)精度：誤差1秒/月（具有微調(diào)設(shè)置）。二、 方案論證：本實(shí)驗(yàn)可采用并行時(shí)鐘芯片（ds12c887）和串行時(shí)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(wú)需外圍元件，并

2、且ds12c887多了一個(gè)字節(jié)來(lái)記錄世紀(jì)使用的，處在ram的32h單元，但是其他的寄存器定義都相同。由于本實(shí)驗(yàn)用到了stc12c5a60s2直插40p封裝的單片機(jī)、nokia5110液晶屏、獨(dú)立式按鍵、四路2輸入與門并且都是直插的，而且在實(shí)驗(yàn)室做pcb只能是單層板，為了節(jié)約空間和簡(jiǎn)化電路于是就選用了串行時(shí)鐘芯片ds1302。三、 理論設(shè)計(jì)：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(jī)，該芯片不僅運(yùn)行速度快

3、穩(wěn)定驅(qū)動(dòng)能力更大，還為用戶提供了內(nèi)部集成8位/10位可調(diào)分辨率adc模塊(在此設(shè)計(jì)中有用到)，1kb可擦寫eeprom本設(shè)計(jì)中用其設(shè)計(jì)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(shí)時(shí)時(shí)鐘模塊，此模塊采用的是達(dá)拉斯公司生產(chǎn)的ds1302具有閏年補(bǔ)償。此圖為按鍵中斷模塊，在此模塊中每個(gè)獨(dú)立式按鍵都能申請(qǐng)外部中斷及時(shí)處理按鍵按下的值來(lái)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(jì)，和開機(jī)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
