基于STC89C52RC單片機(jī)的數(shù)字時(shí)鐘設(shè)計(jì)






摘要：

    本文論述了用單片機(jī)軟件實(shí)現(xiàn)對(duì)時(shí)鐘的控制，介紹了數(shù)字時(shí)鐘電路的各個(gè)組成部分，運(yùn)用Keil軟件進(jìn)行程序編寫(xiě)與仿真，結(jié)合Proteus軟件對(duì)電路進(jìn)行模擬仿真，調(diào)試用ISP軟件下載到單片機(jī)上，顯示時(shí)間。通過(guò)本設(shè)計(jì)重點(diǎn)突出利用單片機(jī)最小系統(tǒng)、使用最少元件來(lái)研究比較準(zhǔn)確的時(shí)間。
