1、[原创][分享]新手写的多功能电子钟  PostBy：2009-5-2720:33:15刚学的单片机,下面的程序是在学习中断和定时器时写的,已调试通过,多功能电子钟有如下功能:1,可以用来做电子钟2,可以用做报警器(按P3.2时,用做报警)3,可以用做闹钟(按P1.6时,用做闹钟)4,可以显示星期程度当中还有好多的不妥之处,还请高手门帮忙指正.程序如下:(由于注解太多,所以没有能写出来,请见谅!!),制作成功后的图片如附件.内容如下:以下内容只有回复后才可以浏览#include#defineucharunsignedchar#defineuintuns

5、==0){break;}}}}}//报警执行子程序(用P1.7做信号检测脚,同样当P3.6为0时跳出)voidclock(){if(P3_3==0){yanshi(500);if(P3_3==0){clockminite++;if(clockminite==60){clockminite=0;}dispbuf[3]=clockminite%10;dispbuf[2]=clockminite/10;             while(P3_3==0);}}if(P3_6==0){yanshi(500);if(P3_6==0){clockhour++;if(clockhour

6、==24){clockhour=0;}dispbuf[1]=clockhour%10;dispbuf[0]=clockhour/10;while(P3_6==0);}}}//设定闹钟子程序voidkey(){if(P3_6==0){yanshi(500);if(P3_6==0){second++;if(second==60){second=0;}           while(P3_6==0);}}if(P3_5==0){yanshi(1000);if(P3_5==0){minite++;if(minite==60){minite=0;}dispbuf[3]=minite
