毕业设计论文----DS1302八位数码管C语言可调时钟日历.doc

DS1302可调时钟日历程序简介： 8为数码管显示 通过切换时间日历 时间格式位XXXX分别为时分秒 日历格式为XX分别为月日星期在时间显示时，通过按K2实现时、分、秒的闪烁切换 在日期显示时，通过按K2实现月、日、星期的闪烁切换 在任意数码管闪烁时，短按K3，该闪烁位值增1，短按K4，该闪烁位值减1 在任意数码管闪烁时，长按K3，该闪烁位值连续增1，长按K4，该闪烁位值连续减1 在任意调节状态，短按K5，正常显示时间 （程序经硬件实际测试通过，采用共阳数码管，程序放在WORD中有点乱，复制到KILE中就好了）DS1302时钟电路图DS1302程序 #include #define uchar unsigned char #define uint8 unsigned int sbit io_DS1302_RST = P15 ;
