[SOLVED] compilation d'un code en C avec mplab v8 et compilateur c18

[dido1987]

J'ai un erreur bizarre empêche la compilation dans le fichier main dont je veux configurer la port B en sortie j'ai déclaré les bibliothèques
#include <p18f4550.h>
#include <stdio.h>
et j'ai met
set_tris_b(0);
et en plus j'ai essayé
set_tris_b(0x00);
mais l'erreur suivant sorte :
MPLINK 4.14, Linker
Copyright (c) 2007 Microchip Technology Inc.
Error - could not find definition of symbol 'set_tris_b' in file 'C:\Users\Administrateur\Desktop\PIC-USB-fonctionnel\main.o'.
Errors : 1

Link step failed.
BUILD FAILED: Fri Apr 15 14:15:14 2011

j'ai aucune idée comment le corriger !!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

[horace1]

which compiler are you using?

 

[dido1987]

un compilateur postuler par michrochip "mplabc18-v3_37_01-lite-installer"

 

[horace1]

I have never seen

set_tris_b(0);

using mcc18 compiler, I would use

TRISB = 0;

 

[bigdogguru]

I believe set_tris_b() is in CCS compiler lib.

CCS built-in functions

...
set_pwm4_duty( )*
set_pwm5_duty( )*
set_pwm_duty( )+
set_rtcc( )*
set_timerx( )
set_timerxy( )+
set_tris_x( )
set_uart_speed( )
setjmp( )
setup_adc( )
....

Maybe you are using a code snippet written for the CCS compiler, dido1987.

I tayed TRISB=0x00; but it dosen't work the same error
now am thinking perhaps is the CDC configuration of usb code but i dont know were's the mistake

 

[horace1]

it is very strange. I tried the following with mcc18

#include <p18f4550.h>

void main (void)
{
   TRISB = 0x00;
   PORTB = 0;
   PORTB = 0x5A;
   while (1)
    ;
}

which compiled and built OK with the following tools
Language tool versions: mpasmwin.exe v5.37, mplink.exe v4.37, mcc18.exe v3.36, mplib.exe v4.37

check you have the correct PIC18 seleceted in Configure > Select Device

try the above program and if it fails post the full error listing from the output window

Upload your code and I'll take a look at it.

the code is not that small because am traying to write a code for connection between USB and my PIC18f4550,so T took the original code from microchip and reconfigurate with my needs it works but when i put TRISB to send data for PORTB one erreur appear and i searched all the code and i didin't find any thing for portb configuration except what i put in main ""TRISB"and still dont work

 

[bigdogguru]

Can you zip up the whole project directory and upload it? This would make troubleshooting the problem much easier.

 

[dido1987]

this is the code i hope it helps

 

[bigdogguru]

By the way, the compiler error is on line 94 in main.c. What is on line 94?


I just got your code, I take a look and get back with you.

I guess line 94 is TRISB=0x00; . I need to start up my dev system with C18 and see what I come up with.

 

[dido1987]

the line 94 is " TRISB=0x00;" it isen't a strange thing by the way thinks for your help
