24LC512

[Alberto]

Hello , I´m trying to use the eeprom 24LC512 for the first time , I´m using 24512.c driver . A wrote this code , but he´s only reading zero from the eeprom . Is the code right. Could some confirm me the connections of 24LC512 , pin A1 A2 A3 , Wp ,pullups etc
the code:
#define EEPROM_SDA PIN_B6
#define EEPROM_SCL PIN_B7

main()
{
long int i;
BYTE d;
BYTE data;
set_tris_b(0b11000000);

lcd_init();
init_ext_eeprom();
delay_us(100);

delay_ms(400);
data=1;

//wite eeprom eeprom
for(i=0;i<100;i++)
{
data=data+1;
write_ext_eeprom(i,data);
delay_us(10);

}


for(i=0;i<100;i++)
{
d=read_ext_eeprom(i);

printf(lcd_putc,"%u",d);


delay_ms(1000);
printf(lcd_putc,"\f");
delay_ms(1000);

/////
}



}

See this thread for a link to a schematic. It's for a 24LC256, but the
pins are the same, and it shows how to connect them.

Please note on the schematic listed above, the pins are mirrored, due to the IC being placed on the back of the board.
