很奇怪的PICC编译问题

只看该作者 · 2012-9-6 14:08

Mplab软件和PICC编译器，PIC12F509单片机，程序如下

#include<htc.h>
//#include "main.h"
__CONFIG(MCLRDIS&WDTDIS&UNPROTECT&INTRC);    //设置配置位(MCLR脚复位禁止,看门狗关,无代码保护，内部RC振荡)

void DelayUS(unsigned char delay)
{
//while(--delay);
NOP();NOP();NOP();NOP();NOP();
}
void main()
{
while(1)
{
  DelayUS(100);
}
}
#ifndef    __MAIN_H__
#define    __MAIN_H__
#endif
很奇怪的问题，main函数中去掉延时函数，就正常了，只要有一处调用延时函数，就增加200%，10处调用延时函数，就2000%，目前还不知道怎么解决此问题。
另外，烧写进去的程序，20%的程序正常，其余均出现数据混乱程序运行时间不对，但是程序流程还是对的。
另外，同样的Mpalb和PICC编译器，打开别的工程，程序调用延时函数，一切正常，未出现这种提示。

main函数如下写法，就不会出现上面红色字体部分提示

#include<htc.h>
#include "main.h"

__CONFIG(MCLRDIS&WDTDIS&UNPROTECT&INTRC);    //设置配置位(MCLR脚复位禁止,看门狗关,无代码保护，内部RC振荡)

void DelayUS(unsigned char delay)
{
//while(--delay);
NOP();NOP();NOP();NOP();NOP();
}

void main()
{
while(1)
{
;
}
}
