從Error Mssage中看來
是'F_Delay'重複定義

你查一下 F_Delay 是否重複定義

大家好,我是使用C18來進行Build All,在source files加入主程式與指令程式,但卻顯示:

Error - symbol 'F_Delay' has multiple definitions.

請各位前輩,告訴我,是哪裡出錯阿! 謝謝~~~

主程式:
#include <p18cxxx.h>
#include "delay.c"
#define LEFT 0
#define RIGHT 1
void F_Initial ( void );
void main (void)
{
int I_Direction=LEFT;
F_Initial();
while ( 1 )
{
F_Delay ( 5000 );
switch ( I_Direction )
{
case LEFT:
PORTD <<= 1;
if ( PORTD == 128 )
I_Direction = RIGHT;
break;
case RIGHT:
PORTD >>= 1;
if ( PORTD == 1 )
I_Direction = LEFT;
break;
default:
break;
}
}
}

void F_Initial ()
{
TRISD = 0;
PORTD = 1;
}
