include只能是头文件.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里的所有内容，再编译到ds18b20.c时，发现那些函数名已经被主程序声明过了。就出现了重复声明的问题。


所以将#include "ds18b20.c" 改为#include "ds18b20.h"

重复定义了相同的变量

提示全局变量重复定义，是不是uchar unsigned char被重复定义了？你检查一下头文件包含里有没这代码

ERROR L104: 变量重复定义，请参考全局变量；
WARNING L16: 函数没有被调用，如果真的没用就删了。
