1.在*.C檔後面案enter還是不行
2.它一直說 F_Dealy 重複定義 ... 難道課本範例也會錯 XD

你試試看:
在每一*.C檔的最後再按一次enter
例:
void main(void)
{
} //按enter
應該就可以了.

看看F_Dealy這一symbol是否重覆定義.

嗯 ~ 試了半天副程式還是串不起來，我MPLAB從7升到8了還是不行 ? 課本上的設定我也是做了勒 ? 沒有理由按表抄課還會被電腦八掉勒 ><" 這到底是什麼原因勒 ?

BUILD SUCCEEDED

*2.或是Demo版本的差別嗎!

*3.可能須其他先進的幫忙了.

我拿你的編譯完會出現語法錯誤耶
錯誤如下：
MPLAB C18 v3.00 (demo) Copyright 1999-2005 Microchip Technology Inc. Days remaining until demo becomes feature limited: 46 C:\Documents and Settings\Chen Yang Li\My Documents\add2\ext_c.c:6:Error: syntax error Halting build on first failure as requested. BUILD FAILED: Mon Aug 18 12:20:25 2008

我把你的程式也拆成兩部份各存成C
檔名分別為delay 和你打的 ext_c
一樣都 Add Source 底下，然後匯入LKR 都設定好以後 build
還是不行 ~ 應該是軟體設定上不知道哪裡有問題才對
我程式已經都貼出去了就是第一篇

*1.example.c
#include <P18F8622.h>
#include "ext_c.c"
int counter;
void main (void)
{
int i,j;
counter = 1;
TRISB = 0; /* configure PORTB for output */
while (counter <= 15)
{
PORTB = counter; /* display value of 'counter'
on the LEDs */
counter++;
}
i=5000;
j=50;
counter=i/j;
ext(counter);
}

*2.ext_c.c
#include <P18F8622.h>
void ext (int i);
void ext (int i)
{
if(i==0) PORTB=0;
}

*3.程式隨便寫的,沒有問題,看跟你的有何不同?

*4.或將你的程式丟出,我幫你Compile.

主題：MPLINK如何設定使用
課本：宏友 ~ PIC18Fxx2微控制器原理與實作 (使用組合與言語C語言)
書號：H0210
實驗章節：5.7發展大規模的程式 5-42 頁
問題：程式寫到最後的龐大肯定是有副程式來組合完成的，於是就開始
照著課本範例實做看看，可是我build以後出現如下問題
***************************************************
MPLINK 4.00, Linker Copyright (c) 2005 Microchip Technology Inc. Error - symbol 'F_Delay' has multiple definitions. Errors : 1 BUILD FAILED: Mon Aug 18 10:30:08 2008
***************************************************
請問這是我設定上有什麼錯誤嗎 ? 我只是單純的照著課本把範例程式打
開，建立好專案，按下build就這樣而已~還需要設定什麼嗎 ?
1. Project > New 建立專案
2. Sorce File 將C檔案載入
3. 匯入LKR檔
4. 設定好Project Build Options
5. Configure 處理器也設定好了也改成HS
***************************************************
操作完畢以後沒有辦法Build耶 ? 他的程式碼如下：
( 第一段程式 )
***************************************************
#include <p18f452.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;
}
***************************************************
( 第二段程式，要被呼叫的副程式 )
#include <p18f452.h>

void F_Delay ( int );

void F_Delay ( int I_Delay_value )
{
int I_Delay_counter;
for ( I_Delay_counter=0 ; I_Delay_counter <= I_Delay_value ; I_Delay_counter++ );
}
請問各位先進，哪裡有錯呢 ?
