haoDIY创好电子音响电脑科技DIY小制作发明移动版

一、智能电子钟的成果
　1、整日历计时。
    2、12/24小时转换。
    3、8路按时输出（可关/开节制）
    4、偏差：15S+1uS
    5、大、小月，润年，周，自动追踪

二、 调校
　　上电后，电子钟表现“1：00”。
　　1、8路按时时刻查询
　　按下K1键依此表现8路按时时刻。礼拜位表现：“H”暗示：打开当前按时输出；“L” 暗示：封锁当前按时输出。此时按K2键可举办“H”、“L”的切换。全部输出，均由蜂鸣器输出！
　　2、表现状态的节制
　　按下K2键可进入以下事变状态：
    1）12小时/ 日月瓜代表现。
    2）12小时牢靠表现。
    3）24小时/ 日月瓜代表现。
    4）24小时牢靠表现。
　　3、校时
　　按下K2键3S后，进入校时菜单。按下K1键依次进入校时状态：分、时、天、月、年、微调系数。此时按K2键，完成+1。当表现“d”时，暗示要调解微调系数（0-99），其值越小，时钟走时越慢。当行使的6MHz的晶振毛病大时，应细心调解微调系数！当表现“out”时，按K2键，即可退出！退出后，按恣意键即可启动时钟。
　　4、配置按时时刻
　　按下K1键3S后，进入配置菜单。按下K1键依次进入8路按时调解状态：时、分。此时按K2键，完成+1。当表现“out”时，按K2键，即可退出！
