PIC18F2220 Erreur de programme de clignotement de DEL

Question

Je suis un débutant en programmation PIC. This video J'ai utilisé pour coder mon premier programme.

C'est le code que je l'ai écrit:

#include <stdio.h> 
#include <stdlib.h> 
#include "XC8.h" 

void main(void) 
{ 
    TRISBbits.RB0 = 0; 
    OSCCON = 0x76; 

    while(1) 
    { 
     LATBbits.LATB0 = ~LATBbits.LATB0; 

     for (int countDelay=0; countDelay<20; countDelay++) __delay_ms(50); 
    } 
} 

Et mon fichier d'en-tête XC8.h est:

// PIC18F2220 Configuration Bit Settings 

// 'C' source line config statements 

// CONFIG1H 
#pragma config OSC = RC   // Oscillator Selection bits (External RC oscillator, CLKO function on RA6)

// #pragma config statements should precede project file includes. 
// Use project enums instead of #define for ON and OFF. 

#define _XTAL_FREQ 8000000 

J'ai suivi toutes les étapes prévues dans le tutoriel mais je reçois ce qui suit erreur lorsque j'essaye de construire le programme.

Espérons que j'ai ajouté suffisamment de données pour la requête. Puisque je suis nouveau dans cette section, n'hésitez pas à demander de plus amples informations.

Vous manquez d'inclure #include <xc.h>, au lieu de simplement définir vos bits de configuration. Le xc.h est le fichier d'en-tête principal qui comprendra beaucoup d'autres fichiers d'en-tête qui pointent finalement vers le fichier d'en-tête de votre contrôleur spécial #include <pic18f2220.h>. Cela se fait avec les constructions #ifdef que votre IDE MPLAB devrait fournir car vous avez initialement défini le contrôleur lors de la création d'un nouveau projet.

Cette guide from Microchip est très utile car elle commence par beaucoup.

Si vous n'incluez pas le fichier d'en-tête <xc.h>, les noms de registre de votre contrôleur ne sont pas connus du compilateur. C'est la raison de vos erreurs.
