1、單片機(jī)課程設(shè)計(jì)報(bào)告 項(xiàng)目：作息時(shí)間表系統(tǒng)設(shè)計(jì) 班級(jí)：通信工程04本 姓名：xx x號(hào) 實(shí)驗(yàn)指導(dǎo)老師: 李強(qiáng)一、題目作息時(shí)間表系統(tǒng)設(shè)計(jì)用89c51設(shè)計(jì)一個(gè)6位led數(shù)碼顯示“作息時(shí)間表系統(tǒng)”，顯示時(shí)間為000000 23時(shí)59分59秒，每秒自動(dòng)加一。另設(shè)計(jì)4個(gè)按鈕，分別是“分狀態(tài)”按鍵、“分加1”按鍵、“時(shí)狀態(tài)”按鍵，“時(shí)加1”按鍵。用于進(jìn)行小時(shí)和分鐘的調(diào)整。這就是一個(gè)完整的具有時(shí)、分、秒顯示的單片機(jī)實(shí)時(shí)鐘系統(tǒng)。二、增加功能在上述實(shí)時(shí)鐘系統(tǒng)的基礎(chǔ)上，在控制軟件鐘增加一個(gè)“作息時(shí)間表”，如圖1 所示，并增加對(duì)該表的查詢功能模塊，依據(jù)對(duì)該表的查詢結(jié)果，控制喇叭，進(jìn)行課間打鈴提示，完成單片機(jī)作息時(shí)間表

2、系統(tǒng)的設(shè)計(jì)。也完成本次課程設(shè)計(jì)。三、內(nèi)容提要 本設(shè)計(jì)利用單片機(jī)的定時(shí)器/計(jì)數(shù)器定時(shí)和記數(shù)的原理，結(jié)合sl-100、sl-200系統(tǒng)上的集成電路芯片8052、led數(shù)碼管以及按鍵來設(shè)計(jì)計(jì)時(shí)器。將軟、硬件有機(jī)地結(jié)合起來，使得系統(tǒng)能夠正確地進(jìn)行計(jì)時(shí)，數(shù)碼管能夠正確地顯示時(shí)間。其中本設(shè)計(jì)中的四個(gè)開關(guān)按鍵：其中一個(gè)按鍵按下去時(shí)，系統(tǒng)進(jìn)入秒調(diào)整狀態(tài)，然后，秒加1鍵每按一次，秒計(jì)時(shí)器加1。時(shí)狀態(tài)按下時(shí)，系統(tǒng)進(jìn)入時(shí)調(diào)整狀態(tài)，時(shí)按鍵每按一次，時(shí)計(jì)數(shù)器加1。本設(shè)計(jì)運(yùn)行開始時(shí)，各按鍵回到各初始位置，即都處于1狀態(tài)。計(jì)時(shí)顯示從00：00：00開始，依據(jù)秒加1為單位進(jìn)行顯示計(jì)時(shí)。三、實(shí)驗(yàn)?zāi)康?1、 通過本次課程設(shè)計(jì)加深

3、對(duì)單片機(jī)課程的全面認(rèn)識(shí)復(fù)習(xí)和掌握，對(duì)嵌入式系統(tǒng)的應(yīng)用進(jìn)一步的了解。 2、 掌握定時(shí)器、外部中斷的設(shè)置和編程原理。 3、 通過此次課程設(shè)計(jì)能夠?qū)纹瑱C(jī)軟硬件結(jié)合起來，對(duì)程序進(jìn)行編輯，校驗(yàn)。四、意義 該實(shí)驗(yàn)通過單片機(jī)的定時(shí)器/計(jì)數(shù)器定時(shí)和計(jì)數(shù)原理，設(shè)計(jì)單片機(jī)作息時(shí)間表系統(tǒng)，擁有正確的計(jì)時(shí)、顯示、時(shí)間調(diào)整等功能，并同時(shí)可以用數(shù)碼管顯示，在現(xiàn)實(shí)生活中應(yīng)用廣泛，具有現(xiàn)實(shí)意義。五、本人所做工作根據(jù)相關(guān)的單片機(jī)材料，利用所學(xué)的單片機(jī)知識(shí)，結(jié)合sl-100單片機(jī)微機(jī)實(shí)驗(yàn)系統(tǒng)中的軟件和硬件（集成電路芯片8952，七段數(shù)碼管，開關(guān)電路及時(shí)鐘信號(hào)電路，按鍵等），編寫能夠?qū)崿F(xiàn)該設(shè)計(jì)的軟件程序，最后將軟、硬件有機(jī)的結(jié)合

4、起來，進(jìn)行有效的調(diào)試，達(dá)到完成該實(shí)驗(yàn)課程設(shè)計(jì)的目的要求。六、設(shè)計(jì)內(nèi)容用at89c51設(shè)計(jì)一個(gè)6位led數(shù)碼顯示“實(shí)時(shí)鐘”，顯示時(shí)間為00：00：00秒，每秒自動(dòng)加一。另設(shè)計(jì)一個(gè)“時(shí)狀態(tài)”按鍵和一個(gè)“時(shí)加1 ”按鍵。再增加一個(gè)“分狀態(tài)”按鍵和一個(gè)“分加1”按鍵。在以上設(shè)計(jì)的基礎(chǔ)上，在在控制軟件系統(tǒng)中增加作息時(shí)間表功能，驅(qū)動(dòng)喇叭去完成作息時(shí)間控制的功能。七、設(shè)計(jì)思路及描述該實(shí)驗(yàn)要求進(jìn)行計(jì)時(shí)并在數(shù)碼管上顯示時(shí)間，則可利用sl-100單片機(jī)實(shí)驗(yàn)系統(tǒng)中的芯片at89c52，中的p3管腳做為外部按鍵輸入，并實(shí)現(xiàn)各個(gè)按鍵的功能；定時(shí)器t0作為每1050毫秒加一的定時(shí)器。在內(nèi)部ram中開辟1050ms計(jì)數(shù)器，

5、秒計(jì)數(shù)器、分計(jì)數(shù)器、時(shí)計(jì)數(shù)器。單片機(jī)依據(jù)定時(shí)器t0的定時(shí)時(shí)間，進(jìn)行秒、分、時(shí)的累加，并將秒、分、時(shí)數(shù)據(jù)轉(zhuǎn)換為7段led顯示段碼，送led顯示器，從而完成單片機(jī)實(shí)時(shí)鐘系統(tǒng)的設(shè)計(jì)。注意，為了輸出顯示方便，時(shí)、分、秒的累加計(jì)時(shí)可以采用bcd碼運(yùn)算。 。八、原理圖九、課程設(shè)計(jì)參考匯編程序 ;*; 按鍵可調(diào)作息時(shí)間電子鐘; ;date 2007.7.6 ;created by 李強(qiáng) ;*;*; 顯示緩沖區(qū)定義;*seclequ50hsechequ51hminlequ52hminhequ53hhourlequ54hhourhequ55h;*; 時(shí)鐘計(jì)數(shù)單元定義;*msequ56hsecequ57hmine
