I2C addresses

I'm programming an I2C driver for a EEPROM chip (M24C08).

As, in my device E2 is 1, the 7 bits addres of the device is 0xA8, insn't it?

What is the meaning of the parameter I2C_InitStructure.I2C_OwnAddress1? Which value should I have in this field?

The EEPROM is the only device in the bus.

Thanks.

I vaguely remember that I2C_OwnAddress1 might be the stm32 (main) I2C address when the macrocell is used is slave mode.

So then should be any address different from the address of the rest of the devices, shouldn't it?

in what mode? if you don't know what slave and master modes are, please read the manual.
