ds1302 的.c .h 程序都是复制的没问题啊，就单独显示时钟是可以的，加到这个程序就不行了，串口发到电脑上也是？？？问号

不是这样的，用c

你这样的开发版，应该有历程的，所以，找个历程下载进去，看下行不行。
然后，就是硬件问题了。我记得当时是那个芯片坏的，一直读取不了。然后，电池也是没电的，也是不行。

为什么没贴1302部分的程序呢，试试把1302部分的操作频率降低，有的1302芯片好像数据的时钟频率不能太高了

单独1602显示可以的，加到我这个程序就不能显示了

1302的程序就是复制的开发板历程里面的，我在1602单独显示或者串口传回电脑可以有1302的值，

这么长的程序实在没耐心看完。。。我觉得写代码的时候应该先实现小的功能模块并测试OK然后再逐步增加其它功能模块，这样全部写完再测试根本没办法判断问题可能出现的地方，然后出错后可以用printf在特定位置打印代码，方便判断具体执行情况。

最好还是一种种功能来实验，先做好LCD1602，再DS1302,后AT2402.一口吃个大胖子不切实际！
