這次發(fā)帖也是因?yàn)閯偨柚?1黑電子論壇里的資料完成一件洞洞板制作的作品。所以也想來賺點(diǎn)黑幣，我不是大神，只是個(gè)小白。附帶吧內(nèi)大神資料，
程序名稱：六位數(shù)碼管時(shí)鐘表
編譯器：Keil uVision 4
程序功能：上電后，程序按初始時(shí)間開始時(shí)鐘演示，時(shí)間顯示按24小時(shí)制。
時(shí)間調(diào)整：按A鍵，顯示加1，按B鍵，顯示減1，按C鍵，清零
MCU：AT89C51
晶振：11.0592M
外圍部件：
鍵盤：4按鍵A、B、C、D分別接在P1.0、P1.1、P1.2和P1.3上，低電平有效
A、B、C鍵分別控制時(shí)、分、秒的選擇，D鍵銨下進(jìn)行時(shí)間調(diào)整。
顯示：4位共陰極LED，P0口送顯示數(shù)據(jù)，P1口低四位位選
內(nèi)部資源：
使用定時(shí)計(jì)數(shù)器1中斷，用于定時(shí)及顯示
警告：
1. 按鍵未加防抖動(dòng)程序
2. 此程序經(jīng)過編譯并通過Proteus仿真，未通過實(shí)物檢驗(yàn)。
