PICC18编译提示出错的是:

GLCD_Wrchs(0,0x8,byX,0);两个语句下提示：

程序结构在Keil C51下编译很正常,其实也是用过的一些函数定义。现在移植到PICC18下使用就不正常了。可能也是我的C语言功底薄了，不知怎么办了

#include "pic18f4620.h" //register 定义

only a moron will code that way.

//#include "htc.h"

I wonder why you would comment it out.

__CONFIG(3, 0x8000);

you are going out of your way to make your life more difficult than necessary.

#define __CONFIG(w,s) asm(" global __config" ___mkstr(w));
asm(" __config" ___mkstr(w) " equ "
___mkstr(s))
/* Program a particular configuration word register with a
* literal value (e.g. __PROG_CONFIG(1, 0x0800)). Using this

6楼-- · 2020-02-08 23:39

用后面的配置方法吧。 __PROG_CONFIG(n, x)。前面的我一直不大明白。

帮你编译了一下，有几处地方是错的。不能用#include "pic18f4620.h" 改用#include "htc.h"，我一般是#include "pic18.h"
