Due to the development of the digital integrated circuit technology and adopts the advanced quartz technology, walking make digital clock has advantages of accurate, stable performance, easy to carry, it is also used in timing, automatic feed and automatic control and other fields. Although already on the market at present the readymade digital clock chip for sale, cheap, use is convenient, but in view of the single chip microputer timer function also can plete the design of the digital clock circuit, therefore is necessary for the design of digital clock. Here we will have learned more fragmented knowledge of digital circuit of the anic link, the system used in practice, to develop our prehensive analysis and circuit design, programming, debugging circuit ability. SCM has small volume and powerful function, high reliability, low price and a series of advantages, not only has bee widely used in the field of industrial measurement and control intelligent control instruments, and has perated into every corner of the people work and life, effectively promote the industry39。s technological transformation and upgrading of products, the wide prospect of application. Keywords: Single chip microputer,Digital clock. 目 錄 第一章 設(shè)計(jì)方案 1 課程設(shè)計(jì)目的 1 設(shè)計(jì)要求 1 實(shí)現(xiàn)時(shí)鐘計(jì)時(shí)的基本方法 1 電子鐘的時(shí)間顯示 1 電子鐘的時(shí)間調(diào)整 2 總體方案介紹 2 計(jì)時(shí)方案 2 控制方案 2 第二章 系統(tǒng)硬件 電路設(shè)計(jì) 3 單片機(jī)模塊設(shè)計(jì) 3 芯片分析 3 晶振電路 4 復(fù)位電路 5 數(shù)碼顯示模塊設(shè)計(jì) 5 按鍵模塊 8 第三章 系統(tǒng)軟件設(shè)計(jì) 9 軟件設(shè)計(jì)分析 9 系統(tǒng)軟件設(shè)計(jì)流程圖 9 主程序流程圖 9 定時(shí)器流程圖 9 按鍵檢測(cè)流程圖 10 時(shí)間顯示流程圖 1
