unsigned char yi,er,san,si,wu,liu,qi,ba;

include只能是頭文件.h不能是.c文件。。。主程序
#include "ds18b20.c"
表示你在主程序里包含了ds18b20.c里的所有內容，再編譯到ds18b20.c時，發現那些函數名已經被主程序聲明過了。就出現了重復聲明的問題。


所以將#include "ds18b20.c" 改為#include "ds18b20.h"

重復定義了相同的變量
作者: 1105688209    時間: 2020-4-22 12:58
提示全局變量重復定義，是不是uchar unsigned char被重復定義了？你檢查一下頭文件包含里有沒這代碼

ERROR L104: 變量重復定義，請參考全局變量；
WARNING L16: 函數沒有被調用，如果真的沒用就刪了。
