multi slave in I2C bus

Ranjan Nayak

Please help me at C code for reading time from DS1407 on I2C bus.I am able to R/W data to an EEPROM on the same bus.But when i read the time i get 0xffff for hrs,mins and secs even after initializing the RTC chip.

    Of course i have gone through the note and i did not find any difference in communication protocol between EEPROM and RTC except EEPROM operates in 16 bit addressing mode whereas 8bit in case DS1307.

    And more ever i have tried it by removing the EEPROM from the same bus. still am unable. please help me out..

    thanks
