单片机 秒表

跪求单片机c51一个多功能时钟设计。要闹钟。调整时间、秒表、就行了。急求。。。C语言编写

//给你发一个数码管输出的可调节时钟的程序，在最后#include #include //定义共阳极字型码0123456789-unsigned char code dispcode[]={0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,0x80,0x90,0xbf};unsigned char time[]={0,0,0,0,0,0,0,0};//用来储存时间unsigned char date[]={0,0,0,0,0,0,0,0};//用来储存日期SYSTEMTIME time1; //在ds1302。 h文件中已经定义了一个名字为SYSTEM...全部
