Communication between ADAU1442 and PIC16F877 microcontroller

Hello Everyone,

I am new in DSP field and I want to enable communication between the ADAU1442 and the SigmaStudio programming tool via the PIC16F877 microcontroller, where I want to glow led on Analog GPIO board in this project communication established using i2c but after doing lots of coding and testing it does not work, where is I checked i2c on the analyzer and it read and write data But still, GPIO board led not glow. I attach my both sigma studio and MPLAB project see them and please give some suggestion why it not works?

Thank you in Advance.
