44 experimental platform to plete the digital clock experiments, so that we clearly understand our side of the digital clock function is how to achieve. Digital clock experiment consists mainly of two basic functions of the body clock circuits, alarm circuits. The main one: mainly related to mold 60 and the mold 24 counters, dynamic display control circuit, the whole point timekeeping main divider circuits, which are packaged in modules, so that other circuits calls. To constitute a timing counter parts, through the separation of the 1HZ divider pulse timing, called dynamic display circuit display, through the whole point timekeeping circuit control buzzer. Subject II: mainly related counter mold 60 and the mold 24, a display control circuit, four data parator. Mold 60 and the mold 24 to form counter timing and memory circuit, 5 called dynamic display control circuit shows that by four data parator pares the clock and the alarm hour, minute, and followup with the door control buzzer. 關(guān)鍵詞 : MAX+Plus2 軟件 EPF10K10LC844 數(shù)字時(shí)鐘 基本功能電路 鬧鐘電路 6 實(shí)驗(yàn)一 題目: Max+Plus2使用練習(xí),完成一個(gè)簡(jiǎn)單門電路的 圖形 設(shè)計(jì)輸入、編譯、仿真、管腳分配、下載。 主體一:主要涉及模 60 與模 24 計(jì)數(shù)器、動(dòng)態(tài)顯示控制電路、分頻器主要整點(diǎn)報(bào)時(shí)電路, 這些電路都是以模塊封裝好的,以便其他電路調(diào)用。 21 附件 19 四 .討論與心得 13 時(shí)模塊 10 二.各模塊設(shè)計(jì) 原理 10 11 數(shù)字時(shí)鐘 實(shí)驗(yàn)主要包含兩個(gè)主體 時(shí)鐘基本功能 電路、鬧鐘電路。以模 60 與模 24 計(jì)數(shù)器構(gòu)成定時(shí)與存儲(chǔ)電路,調(diào)用動(dòng)態(tài)顯
