Interfacing AD7730

Hi every one I was looking for any similar post for days.....

I want to interface AD7730 Bridge Transducer ADC with a PIC.

The project it is still in Demo Mode and it's simple in main loop.

So here is the schematic

I was wondering if anyone has done this before because I need some help.

After my PIC initialization the fisrt think I do is to read the Status Reg. of AD7730 . Things seems to be fine according to the datasheet. Reset value is CX and I read C1.

I after some AD7730 configurations I read data reg. all the time. But it returns zeros all the even I had connected a load cell.

I followed the guide (pseudo code) from the manual but is not working.

Thanks In Advance
