WARNING L7: MODULE NAME NOT UNIQUE
函数重名
WARNING L1: UNRESOLVED EXTERNAL SYMBOL
无法定位的外部符号（那个变量没有定义或者打错了）
WARNING L2: REFERENCE MADE TO UNRESOLVED EXTERNAL
调用了未定义的符号，其实可能是只有一处错误

大哥~这样看不清楚的~你直接发程序过来~发来我邮箱~我帮你看~yumengquan@qq.com

MS出现这种错误时因为没有指定器件的类型。

没见过这么多的错误，你是怎么弄出来的？

具体请查阅KEIL帮助文档BL51.chm（在安装文件夹下的\C51\HLP子文件夹里）中的“Error Messages”有关L7、L1、L2的详细解释。
