hi,
did you wached the line of the i2c bus (a scope or logic analyzer)
if you do not have such equipment use a software i2c master (easier to debug)
and 2 multimeters, one for each line. run stepping through the code and see if
there is a problem.
if it is working then you have a speed related problem or a flow in the code
when using the hardware on the chip. to check if there is a speed related
problem use a scope or try running the i2c at low speeds.

hi !!!
I am having problem with reading and writing data to FRAM using the I2C
bus. I am using FM24CL16 connected to MSP430F1610. I have tried using
the sample application code of EEPROM+I2C on the same ( i changed the
address of FRAM) , but im unable to read and write. The problem is that
I2CDRB register doesnt get updated with the new value.
Can someone please tell me how to go about ?
Thanks in advance for any help
