Regarding I2C communication on the ADXL345 Z eval board.

Hi,

 

   I am trying to communicate via I2C to the ADXL345Z board. I have hooked up the board with all the necessary connections with the pull ups of 10K.   The host is a MSPEXP430F5438 experimenter board with a MSP430F5438a chip. When I try to send the START bit I am not getting any response from the ADXL345. In my scope I can see the line getting pulled up and also the data being sent. In the website they say that since no processor is present in it the host has to program the firmware (http://www.analog.com/en/evaluation/eval-adxl345z/eb.html)  I am not sure how to do that. How can I fix this? Any help would be greatly appreciated.

 

Thanks.
