ad7730 interfacing problem

i recently purchased a ad7730 to measure readings from a 2 ton load cell. but i am not able to communicate with ad7730 at all. I am using a atmega32 microcontroller please help me immediately as my project solely depends on the load cell. I am attaching the code which i wrote to communicate with ic but no result everytime i get 00 or ff value. it would be very great help if i could get a proper connection diagram of ad7730 with my microcontroller.

  • Hi p_d,

         There is ADI wiki page that you may want to check. Please refer to the link below. There is a software driver for the AD7730. Although the driver was based from the AD7730 evaluation board. But this can serve as your reference. Hope this help.
