编译, PIC18, PICC18, 单片机C, CD

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。

找到一个BUG了,函数void GLCD_Wrchs(uchar cx,uchar cy,uchar * chrt,bit beng_chn); 多加一个 const,即在uchar * chrt前加,就行了.现在还是配置CONFIG出错

#include "pic18f4620.h" 改成#include "htc.h"，CONFIG配置位的问题不再提示了，但出现如下错误

Advisory[1234]  * Corrupted fast interrupt shadow registers
Advisory[1234]  * Data in RAM location can be corrupted if async. reset occurs during write
