实钟程序,通过89C52让1602液晶显示出实钟,通过key1键(功能键)设置日期,时间,key2键为按一次时间或日期加1,key3为按一次时间或日期减1,现在,更改日期时间还有时间走秒走分走时都没问题,就是小时每到24小时后星期不知道要怎么显示往前进一天,我只能实现经过24小时后星期往前进一天,但是再过24后,星期就不往前进一天了,不知道要嵌套在哪里,有没有帮帮忙的,程序如下:

小平头技术问答
你写的也忒麻烦了,要是我就这样写 uint32 Second;//秒计中断++计数 LCD_Display(Position,Second/(60));//分 LCD_Display(Position,Second/(60*60));//小时 LCD_Display(Position,Second/(60*60*24));//日期 LCD_Display(Position,Second/(60*60*24*7));//星期 LCD_Display(Position,Second/(60*60*24*365);//年
你要是没有时钟芯片掉电不就没了吗?
[ 本帖最后由 huo_hu 于 2011-10-14 17:59 编辑 ]LZ,你这程序有好几个问题
1、数据没初始化,你LCD是1月1日,但是ye(不应该是yue吗)和ri的值却是0,其实建议变量用英文别用中文拼音
2、调日期没法自动对准星期,
3、你直接默认当天是SAR(星期六不是SAT吗),下一天是SUN了,所以你table2只有SUN啊,你怎么可能输出其余的日期·····
4、竟然每个月都31天,这个问题都没注意,估计调整年月可能出现的日溢出也没考虑吧
5、不知道为啥你年不设置减的,不减就不减吧,也没事
6、时钟过0点,日期不会变
修改程序如下:
