I have an AT90S8515 and I want to interface it with a 24C32A (I2C EEPROm). functions of Codevision (in its help) do not work properly and I cant send and receive data from eeprom. Is there any body who can help me? Thanks in advance. Regards.

I used pull up resistors. It was because of addressing for EEPROM. its address in memory location is 14 bit and I used 8 bit for addressing. Regards, K1
