[mortaurat]

Bonjour
j'ai un petit probléme avec le programme suivant.

#include <16f877A.h>
#use delay (clock = 2000000)

#define  rs  PIN_A5                    //COMMNAD/DATA SELECT           
#define  rw  PIN_A4                    //READ/WRITE SELECT             
#define  e   PIN_A3                    //ENABLE SIGNAL                 
#define  psb PIN_A2                    //PARALLEL/SERIAL 
#define  rst PIN_A0                    //RESET SIGNAL   


void lcd_init();                    //LCD init       

//initialisation du LCD 
void lcd_init()
{
  rst=0;                         //reset LCD
  delay_us(10);                       
  rst=1;                         //LCD normal work.
  psb=1;                         //8 bit as parrallel.
}

pour rst=0; rst=1; et psb=1; il me sort expecting LVALUE such as variable name or *expression.

Avez vous une idée ?

Salut.
Si tu mets PIN_A5=0; ça marche ?
Si non, regarde dans les noms des sorties dans le fichier 16f877A.h

[mortaurat]

Non toujours la même erreur.
Et le nom de sorti est bien PIN_Ax.

Je pense qu'il doit y avoir une erreur avec l'extension .c ou .h

[sdec25]

Et le nom de sorti est bien PIN_Ax.

Poste le contenu du fichier .h (au moins la partie où il y a PIN_Ax s'il est trop gros).

j'essaye de faire une librairie pour mon afficheur LCD.
Si dans "mondriver.c"
j'ecris:

#define  rs  PIN_A5                    //COMMNAD/DATA SELECT
#define  rw  PIN_A4                    //READ/WRITE SELECT

#define  psb PIN_A2                    //PARALLEL/SERIAL 
#define  rst PIN_A0                    //RESET SIGNAL   

void lcd_init();                    //LCD init       

//initialisation du LCD 
void lcd_init()
{
  rst=0;                         //reset LCD
  delay_us(10);                       
  rst=1;                         //LCD normal work.
  psb=1;                         //8 bit as parrallel.
}

il me sort a #DEVICE required before this line ....

[sdec25]

Donc les constantes PIN_Ax ne sont que des identifiants, pas des variables.
La solution est donnée dans le .h :

// Discrete I/O Functions: SET_TRIS_x(), OUTPUT_x(), INPUT_x(),
// PORT_x_PULLUPS(), INPUT(),
// OUTPUT_LOW(), OUTPUT_HIGH(),
// OUTPUT_FLOAT(), OUTPUT_BIT()
// Constants used to identify pins in the above are:

Essaie Output_High(PIN_Ax) par exemple.
Si tu trouves ça trop lourd on peut lier les ports à des struct.

[sdec25]

il me sort a #DEVICE required before this line ....

Il faut sûrement préciser le PIC avec #device.
Regarde dans la doc de ton compilateur, normalement tout y est expliqué.

[mortaurat]

Oki,
je vais faire des output_hight et output_low, ca a l'air de marcher.

Merci

[invite93d0bd01]

bonjour
tu peu pas affecter directement une valeur à l'une des pins du pic,
alor au lieu d'écrire :

rst=0;
delay_us(10);
rst=1;
psb=1;
tu doit ecrir ce qui suit:
output_bit(rst,0);
delay_us(10);
output_bit(rst,1);
output_bit(psb,1);

je l'ai testé et ca marché.....

[invited2a6aeca]

Je crois que hassene3985 a trouvé la solution, n'oubli pas que la broche A4 de ton PIC a besoin d'un pull-up pour que ta broche de sortie fonctionne.
