帶兩個(gè)鬧鐘的LCD1602屏小型單片機(jī)萬(wàn)年歷制作

ID:88481 · 發(fā)表于 2018-7-27 20:03

本設(shè)計(jì)中,在按鍵處理方面,下了不少功夫,雖然只有三個(gè)按鍵,不同狀態(tài)下,實(shí)現(xiàn)不同的功能.
為了節(jié)省用電,設(shè)計(jì)背景燈有按鍵銨下才亮,延時(shí)5秒后滅.長(zhǎng)按K1進(jìn)入設(shè)置狀態(tài),按K2移位,K3數(shù)字加.依次設(shè)置年月日,星期,時(shí)分秒,鬧鐘1,鬧鐘2.
在走時(shí)狀態(tài)下,按K2顯示鬧鐘1,按K3顯示鬧鐘2,延時(shí)5秒后返回走時(shí).在顯示鬧鐘狀態(tài)下,按K1,開(kāi)關(guān)鬧鐘,顯示"*"為開(kāi).走時(shí)狀態(tài)下顯示"%"為只有一個(gè)鬧鐘開(kāi),顯示"@"為兩個(gè)鬧鐘開(kāi).在鬧鐘響鈴時(shí),按任意鍵關(guān)閉聲音.
