AD7760 standalone sample code?

Hi, I'm wondering if anyone has the sample code for interfacing the AD7760 in standalone mode, without ced1z board? The most important part of the code is the sequence which starts the ADC as described on page 21 of the datasheet. I started the project over the year ago and my code does not work on the DIY board nor the evaluation board.

 

The DRDY pin outputs 2,5V constantly, which means that new conversion data is not available. I wrote to the register 2 and 1 with the proper delays.

 

Seems like JohnnyG send the sample code to someone via e-mail 3 years ago, but I don't know how to contact him.

 

Update: I've set the Register 1 to read various register values. One at a time. It gives me the same values at every read, like all register had the same value. It means there is something wrong with communication, but I'm not sure what. The clock is applied. I don't use SYNC pin, because I've got only 1 ADC, maybe that's the issue?
