基于51單片機(jī)的數(shù)字時(shí)鐘的方案畢業(yè)方案說明書

1、基于51單片機(jī)的數(shù)字時(shí)鐘的設(shè)計(jì)I畢業(yè)設(shè)計(jì)畢業(yè)設(shè)計(jì)基于基于51單片機(jī)的數(shù)字時(shí)鐘的設(shè)計(jì)單片機(jī)的數(shù)字時(shí)鐘的設(shè)計(jì)摘要：現(xiàn)代生活中，對(duì)于數(shù)字電子鐘的使用情況已經(jīng)遠(yuǎn)遠(yuǎn)大于對(duì)于機(jī)械表的使用。數(shù)字時(shí)鐘不僅僅是使用方便，而且由于單片機(jī)的引入，額外增加了自動(dòng)控制和鬧鐘報(bào)時(shí)等功能，十分便利。本次畢業(yè)設(shè)計(jì)，是以STC89C52芯片為核心，添加適當(dāng)外圍電路，輔以C語言，所形成的數(shù)字電子鐘。除了51單片機(jī)芯片，還主要用到了時(shí)鐘芯片DS1302和型號(hào)是1602的液晶
