摘要

單片機以其體積小、編程靈活、控制功能強大、價格低廉等特點被廣泛應用在各種電子電器產(chǎn)品中。單片機技術(shù)的出現(xiàn)和發(fā)展帶來了電子技術(shù)和控制領(lǐng)域的一場革命。

單片機課程作為職業(yè)院校電子信息類專業(yè)一門重要的基礎(chǔ)課程，它既是一門很有實用價值、實踐性很強且很有趣味性的課程，同時它又是一門集硬件電路設(shè)計與軟件編程于一體的學科，既要求我們有較好的電工電子技術(shù)基礎(chǔ)知識，又要求有一定的邏輯思維和軟件開發(fā)（編程）能力。通過近幾年對單片機的學習，我已掌握單片機的基本知識，并具備了單片機應用系統(tǒng)的初步開發(fā)能力。即將畢業(yè)之際，我運用我所掌握的單片機知識設(shè)計和制作了一個基于51單片機的可調(diào)數(shù)碼日歷鐘，這既是對我所學知識的總結(jié)與高度概括，同時也將自己所掌握的知識與實際應用結(jié)合起來，進一步提高工程實踐能力。

數(shù)碼日歷鐘是實際生活中應用較多的一個電子計時裝置，可供人們查詢?nèi)掌凇⑿瞧诩罢莆諘r間。本文首先從數(shù)碼日歷鐘的功能要求入手，對設(shè)計任務進行了分析，并將任務分解為若干個模塊，提出在設(shè)計與制作過程中要用到的相關(guān)知識點，給出了本設(shè)計的硬件電路及軟件流程，還給出了部分模塊的源程序代碼。本設(shè)計經(jīng)過多次調(diào)試運行無誤，最終提交出一個完整的應用系統(tǒng)產(chǎn)品。

本次畢業(yè)設(shè)計的數(shù)碼日歷鐘能在12864液晶屏上顯示出年月日時分秒以及星期幾，還能顯示當前環(huán)境溫度，并能通過按鍵調(diào)整日期和時間，在調(diào)整日期的同時通過相應算法自動實現(xiàn)星期幾的調(diào)整，而且無論是否閏年、任何月份，當日期調(diào)整時都保證不會出現(xiàn)非法日期。數(shù)碼日歷鐘是一個非常實用的設(shè)計與制作，成本低廉，如能進一步完善，具有一定的推廣使用價值。

本設(shè)計任務比較復雜，要考慮的問題很多，C語言的模塊化程序設(shè)計思想較好地解決了這個問題，故本設(shè)計任務采用C語言編程。

1、概述

1.1畢業(yè)設(shè)計的選題背景及制作意義

1.1.1畢業(yè)設(shè)計的選題背景

單片機以其體積小、編程靈活、控制功能強大、價格低廉等特點被廣泛地應用在各種電子電器產(chǎn)品中。單片機技術(shù)的出現(xiàn)和發(fā)展帶來了電子技術(shù)和控制領(lǐng)域的一場革命。

單片機課程作為職業(yè)院校電子信息類專業(yè)一門重要的基礎(chǔ)課程，它既是一門很有實用價值、實踐性很強且很有趣味性的課程，同時它又是一門集硬件電路設(shè)計與軟件編程于一體的學科，既要求我們有較好的電工電子技術(shù)基礎(chǔ)知識，又要求有一定的邏輯思維和軟件開發(fā)（編程）能力。通過近幾年對單片機的學習，我已掌握單片機的基本知識，并具備了單片機應用系統(tǒng)的初步開發(fā)能力。即將畢業(yè)之際，為了將自己所掌握的知識與實際應用結(jié)合起來，進一步提高工程實踐能力，同時也對自己所學知識作以總結(jié)及高度概括向老師匯報，我決定將我的畢業(yè)設(shè)計課題選作基于51單片機的可調(diào)數(shù)碼日歷鐘的設(shè)計與制作，并以此向老師作畢業(yè)匯報。

1.1.2畢業(yè)設(shè)計的制作意義

數(shù)碼日歷鐘是實際生活中應用較多的一個電子計時產(chǎn)品，廣泛地應用在酒店、賓館、車站、家庭及辦公室中，可供人們查詢?nèi)掌凇⑿瞧?，掌握當前時間及環(huán)境溫度。

在上述背景下，需要我運用近幾年在學校學到的單片機知識及開發(fā)技巧設(shè)計和制作出一個功能完善的可調(diào)數(shù)碼日歷鐘。通過這個設(shè)計的制作，必將進一步提高我的工程實踐能力和單片機應用系統(tǒng)開發(fā)能力，將我所學到的理論知識與實際應用結(jié)合起來，做到理論與實踐相結(jié)合，同時也能對我高職階段所學知識作以梳理和總結(jié)。這是一個非常實用的設(shè)計與制作，成本低廉，若將它稍加改進安裝在鏡框或其它工藝品中，則更加實用。如能進一步完善其功能，具有一定的實際推廣使用價值。

1.2數(shù)碼日歷鐘的功能要求

本設(shè)計制作出來的數(shù)碼日歷鐘要求能在12864液晶顯示屏上顯示出年月日及對應的星期幾，當前時間及環(huán)境。而且要求日期和時間可通過按鍵調(diào)整，當日期調(diào)整時，通過相應算法自動實現(xiàn)星期幾的調(diào)整，無論是否閏年、任何月份，當日

摘要

隨著單片機技術(shù)的飛速發(fā)展，在其推動下，現(xiàn)代的電子產(chǎn)品幾乎滲透到了社會的各個領(lǐng)域，有力地推動了社會生產(chǎn)力的發(fā)展和社會信息化程度的提高，同時也使現(xiàn)代電子產(chǎn)品性能進一步提高。

時間對于人們來說總是那么的寶貴，可以說時間和金錢是劃上了等號。準確的掌握時間和分配時間對人們來說至關(guān)重要。因此采用單片機為主的數(shù)碼管為顯示器的電子時鐘就體現(xiàn)出了很大的優(yōu)勢。電子鐘的設(shè)計方法有很多種，但利用單片機制作的電子時鐘更具有編程靈活、便于電子功能的擴充、精確度高、便于攜帶、顯示直觀等特點。

通過利用MCS-51單片機內(nèi)部的定時器/計數(shù)器功能來實現(xiàn)電子時鐘的計時方法。主要由AT89S51芯片和LED數(shù)碼顯示管為核心，構(gòu)成了一個單片機電子時鐘。
