ds1302 的.c .h 程序都是復制的沒問題啊，就單獨顯示時鐘是可以的，加到這個程序就不行了，串口發(fā)到電腦上也是？？？問號

程序有點兒長呀~~

不是這樣的，用c

作者: yousunny 時間: 2018-8-9 11:13
你這樣的開發(fā)版，應該有歷程的，所以，找個歷程下載進去，看下行不行。
然后，就是硬件問題了。我記得當時是那個芯片壞的，一直讀取不了。然后，電池也是沒電的，也是不行。

為什么沒貼1302部分的程序呢，試試把1302部分的操作頻率降低，有的1302芯片好像數(shù)據(jù)的時鐘頻率不能太高了

單獨1602顯示可以的，加到我這個程序就不能顯示了

1302的程序就是復制的開發(fā)板歷程里面的，我在1602單獨顯示或者串口傳回電腦可以有1302的值，

這么長的程序實在沒耐心看完。。。我覺得寫代碼的時候應該先實現(xiàn)小的功能模塊并測試OK然后再逐步增加其它功能模塊，這樣全部寫完再測試根本沒辦法判斷問題可能出現(xiàn)的地方，然后出錯后可以用printf在特定位置打印代碼，方便判斷具體執(zhí)行情況。

最好還是一種種功能來實驗，先做好LCD1602，再DS1302,后AT2402.一口吃個大胖子不切實際！
