单片机用C语言设计跑表和时钟，由按键控制

Question

是四个数码管，跑表和时钟两个程序，硬件上按键为三行四列，从上往下从右往左依次为 * 7 4 1
0 8 5 2
# 9 6 3
跑表设计
1.按*开始时钟计数格式，第一格10S，第二格1S，第三格0.1S，第四格0.01S，前两者为60进制，后两者为100进制
2.当按0——9中任何一个数，即把当前的时钟值存储下来
3.按#停止计时，此时按0——9键即可查看10组时间值
时钟设计
1.上电后首先执行时钟，格式：MM：SS
2.按*执行时钟调整，再按*退出调整，继续时钟
3.按#执行设定闹钟，再按#退出设定，继续时钟，当时钟到达设定值时，四个数码管只显示g的那条横线
两者会编一个就行，但一定要对！

Answer 1

300我帮你搞定 没这个数不想动脑筋
