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.

    Your code is for a Microchip PIC

    Thank you so much Mr Henry

    A lot of thanks for your co-operation. Indeed i knew that. But i was so ponder with the mistake and i wanted some body to analise. Some of your questionnaire led me to review the hardware and i took the RTC segment to a separate board other than my working mother board which comprise of few more devices like EEPROM and shift registers. Now i con able to communicate with DS1307 and can reed the subsequent registers as well. But as you know still there is more to do. I will let you know the further growth definitely.

    Thanks again.
