还有错误麻烦看看

追答

我编译没有问题的，你那里出错是因为你工程中有startup.a51这个东东，你将之去掉就OK了。

Answer 2

C语言本身允许内联汇编，直接写C语言程序就可以。
C语言和汇编本身结合的比较紧，多看看C语言编译器手册，上面一般都有怎么和汇编混合。
写内联汇编要注意C编译器需要的寄存器需要保护。

梦想之所以被称为梦想，就是在于它是要不断追逐的。

Answer 3

自己改吧 第151行 MOV A,MIN L 改为 MOV A, MIN ; L 就可以了
还有 最后面 ; 查表指令 前面加 ;

Answer 4

第132行 MOV A,MIN L 改为 MOV A, MIN

Answer 5

Keil默认是不生成HEX文件的，需要勾选
