51黑有你更精彩

ID:163010 · 发表于 2017-1-27 16:05

经过测试果然能用，万能的51黑啊

为什么用proteus仿真楼主的电路时四个按键没有用，话说我最近也在做这个时钟，同样也是按键不起作用，不知道是怎么回事

ID:247636 · 发表于 2017-11-10 09:07

课程设计我正在做这个，可是出现了好多自己还不能解决的问题

ID:367145 · 发表于 2018-7-9 09:13

非常好的一个作品。楼主真棒

ID:338810 · 发表于 2018-9-28 16:27

5黑币，黑币不好弄啊！下载试下功能看如何

ID:713966 · 发表于 2020-4-27 19:06

求大神帮助！！能否将倒计时改成阴历月份、日期显示，再加上一个闹钟定时电路，增加K5键？最近在学习你的设计，自己改了倒计时增加农历和闹钟，但程序不知道怎么改，求帮忙，谢谢！！
