課程設(shè)計(jì)目的學(xué)習(xí)單片機(jī)原理，并設(shè)計(jì)電子時(shí)鐘。1.2 課程任務(wù)設(shè)計(jì)的電子時(shí)鐘具有以下功能：（1） 、選擇LCD顯示，可顯示年、月、日、時(shí)、分、秒。（2） 、會(huì)使用實(shí)時(shí)鐘芯片DS1307。（3）

課程設(shè)計(jì)意義通過自己動(dòng)手設(shè)計(jì)制作單片及組成的器件，深入了解了單片機(jī)的實(shí)際應(yīng)用，能更深地理解課堂上所學(xué)的內(nèi)容，使得單調(diào)的理論知識(shí)與實(shí)際聯(lián)系起來，幫助我們更好的理解。第2章 設(shè)計(jì)原理及總體方案選擇2.1 基本功能簡(jiǎn)述電子時(shí)鐘，通過DS1307芯片提供實(shí)時(shí)時(shí)鐘，并通過LCD12864顯示。DS1307是低功耗、兩線制串行讀寫接口、日歷和時(shí)鐘數(shù)據(jù)按BCD碼存取得時(shí)鐘/日歷芯片。它提供秒、分、小時(shí)、星期、日期、月和年等時(shí)鐘日歷數(shù)據(jù)。除此之外，還具有跑表和鬧鐘的功能。跑表是通過中斷實(shí)現(xiàn)，鬧鐘由蜂鳴器實(shí)現(xiàn)并以歌曲為鬧鈴實(shí)現(xiàn)。本電子時(shí)鐘是由ADUC848芯片、時(shí)鐘與復(fù)位電路、選擇按鍵輸入電路、音頻發(fā)生器、音頻放大器和揚(yáng)聲器、LCD顯示模塊和DS1307芯片這七部分組成。圖2.1

在音樂中使用的各個(gè)固定頻率的音叫音級(jí)。常用符號(hào)C、D、E、F、G、A、B、c、d、e、a1、b1、c2、d2表示，它們對(duì)應(yīng)于鋼琴上的白鍵。兩音之間音高的距離叫音程。在上述音級(jí)中，E與F、B與C之間音高的距離僅為其它相鄰音級(jí)之間距離的一半，稱它們之間的音程為半音音程，而稱其它相鄰各音之間的距離為全音音程。在這些全音音程之間又加入新的半音音級(jí)，用符號(hào)C、D、F、G、A、c、d、f、表示，對(duì)應(yīng)于鋼琴上的黑鍵。音持續(xù)時(shí)間的長(zhǎng)短即時(shí)值，一般用拍數(shù)表示。休止符表示暫停發(fā)音。表2.1

每個(gè)音符分為簡(jiǎn)譜碼和節(jié)拍碼。簡(jiǎn)譜碼為D0-L到SI-H。 在此設(shè)計(jì)程序中，包括了兩個(gè)數(shù)據(jù)表，它們分別存放了已經(jīng)計(jì)算好的、各種音符頻率所對(duì)應(yīng)的、半周期的定時(shí)時(shí)間初始值的高八位和低八位。有了這些數(shù)據(jù)，單片機(jī)就可以演奏從低音、中音、高音，三個(gè)八度的音符。在播放樂曲時(shí)，單片機(jī)根據(jù)音符的不同數(shù)值，從表中找到定時(shí)時(shí)間初始值，送入定時(shí)器即可控制音調(diào)。此外樂曲的數(shù)據(jù)也要寫個(gè)數(shù)據(jù)表，在此設(shè)計(jì)程序中名為：code unsigned char Data_Sheet，表中每三個(gè)數(shù)字代表一個(gè)音符，它們分別為： 第一個(gè)數(shù)字是音符的數(shù)值1234567之一，代表Do、Re、Mi.； 第二個(gè)數(shù)字是012之一，代表低音、中音、高音； 第三個(gè)數(shù)字是時(shí)間長(zhǎng)度，此實(shí)驗(yàn)程序以半拍為單位。 樂曲數(shù)據(jù)表的結(jié)尾處為三個(gè)0,在程序中作為結(jié)束標(biāo)志。流程圖為：鬧鐘主程序流程圖中斷1中斷子程序流程圖：2.3 LCD原理簡(jiǎn)述 1、SMG12864D3 液晶顯示模塊的接口信號(hào)說明： 編號(hào) 符號(hào) 引腳說明 編號(hào) 符號(hào) 引腳說明 1 CS2 片選IC2信號(hào) 11 DB2

接口型液晶顯示控制器，它的每字節(jié)點(diǎn)陣排列方式是縱向排列的，用取模軟件取模時(shí)采用縱向取模方式；還有的液晶每字節(jié)點(diǎn)陣排列方式是橫向排列的，用取模軟件取模時(shí)采用橫向取模方式。不同液晶的取模方向可參考相應(yīng)液晶的使用手冊(cè)。本程序采用縱向取模。2、字節(jié)正序和字節(jié)倒序通常一個(gè)字節(jié)的數(shù)據(jù)按二進(jìn)制排列的話都是最左邊為高位A7，最右邊為低位A0，這就是正序；若LCD的點(diǎn)陣與一個(gè)字節(jié)數(shù)據(jù)的排列順序相反，左邊最左邊顯示的是A0，右邊顯示A7，這就是倒序。豎向排列也一樣，通常數(shù)據(jù)是上面為高位A7，下面為低位A0，是正序。如果LCD模塊的點(diǎn)陣排列正好反了，就是豎向倒序。KS0108控制器的LCD豎向倒序排列圖如下圖所示。 程序流程圖如圖所示。 第三章 音樂播放器硬件電路的設(shè)計(jì)和調(diào)試3.1 復(fù)位與下載模塊 由電容，電位器，按鍵組成復(fù)位電路部分，該電路接于單片機(jī)的RESET端可以通過按鍵達(dá)到手動(dòng)復(fù)位的效果。復(fù)位時(shí)PSEN拉低進(jìn)入下載或調(diào)試模式。 圖 3.1 復(fù)位電路圖 圖 3.2 下載電路圖
