conditional compilation ?

Hi. Excuse me for the response time.

I had arrived at the same solution but I was not satisfied.

I thus have modify the way of writing the address :

# ifdef NIOSII_1

// adresse MAC de la carte en hexadecimal# define ADRESSE_MAC "01:02:03:04:05:06"

# endif

# ifdef NIOSII_2

// adresse MAC de la carte en hexadecimal# define ADRESSE_MAC "11:12:13:14:15:16"

# endif

and I have to create a function ether_aton(ADRESSE_MAC) :

void ether_aton(char *pt_addr_ethernet)

{

int i ;

int adresse_tmp[6] ;

int *pt_int = adresse_tmp ;

// conversion de la chaine ASCII en adresse MAC 48 bits

i = sscanf(pt_addr_ethernet, " %02x:%02x:%02x:%02x:%02x:%02x",

(pt_int + 0), (pt_int + 1), (pt_int + 2),

(pt_int + 3), (pt_int + 4), (pt_int + 5)) ;

// mise au format 8 bits des composantes de l'adresse MAC

for (i = 0 ; i < 6 ; i++)

{

adresse_mac_ethernet = (unsigned char)(adresse_tmp) ;

}

}

Thank you for all.
