) 調(diào)整時間和日期,
只設置了四個按鍵
a, 復位按鍵;
b, 調(diào)整模態(tài)選擇按鍵,切換調(diào)整不同參數(shù);
c, 上調(diào)按鍵,調(diào)整模式下按此鍵被調(diào)整值上調(diào);
d, 下調(diào)按鍵,調(diào)整模式下按此鍵被調(diào)整值下調(diào).
這shi調(diào)整年份時de顯示狀態(tài),LCD第二行末尾顯示"yar".
依此類推,調(diào)整月份時顯示"mth",調(diào)整日期時顯示"day",小時時顯示"hor",分鐘時顯示"min".
3) 軟件部分.
程序中包含一個頭文件"LCD1620.h",此文件中包含有關(guān)LCDde一些顯示函數(shù).
下面shi部分程序原代碼---不知道怎么回事,今天網(wǎng)絡速度比較慢,無法上傳文件.如有需要可與我e-mail聯(lián)系lhy_radio@yeah.net.

此萬年歷程序不足,未盡完善之處:
1) 未設置鬧鐘,只能顯示陰歷陽歷和星期等信息.
2) 后續(xù)應加入溫度顯示,以測定日氣溫
3) 沒有與計算機或其他設備通訊接口
4) 液晶顯示處于常亮狀態(tài),影響壽命.應當設置如果一定時間未操作,顯示屏應關(guān)閉.待有按鍵操作時再打開.這樣才能使LCD壽命更為長久.
5) 程序和硬件中未加入對于LCD背光de控制模塊,無光亮時無法看時間.
