Yes that's right that's this piece of code inserted and it worked, thank you very much
#define SDA_PIN 20 // 20 or 70
#define SCL_PIN 21 // 21 or 71
#define TWI_CLOCK_FREQ 400000
// see eeprom device data sheet for the following values, these are for 24xx256
#define EEPROM_SERIAL_ADDR 0x50 // 7 bit i2c address (without R/W bit)
#define EEPROM_PAGE_SIZE 64 // page write buffer size
#define EEPROM_PAGE_WRITE_TIME 7 // page write time in milliseconds (docs say 5ms but that is too short)
// TWI_MMR_IADRSZ_1_BYTE for 1 byte, or TWI_MMR_IADRSZ_2_BYTE for 2 byte
#define EEPROM_ADDRSZ_BYTES TWI_MMR_IADRSZ_2_BYTE
#define EEPROM_AVAILABLE 1
