i have tired with code :

#include <16f877a.h>
#fuses HS, NOWDT //,// NOPROTECT, PUT, NOBROWNOUT, NOLVP
#use delay(clock=8000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7) // Jumpers: 8 to 11, 7 to 12
#define EEPROM_SDA PIN_C4
#define EEPROM_SCL PIN_C3
#include <2432.c>


main() {



init_ext_eeprom();

write_ext_eeprom(0x01,0x01);
write_ext_eeprom(0x02,0x02);
write_ext_eeprom(0x03,0x03);





while (TRUE);

}

but dont write nothing
i do samething not good ?
