AD5932 not responding

Hi,

I'm trying to generate a waveform with the AD5932 but I can't see nothing on the VOUT pin. I'm writing in the registers with the spi of an atmega32 and I think that the code might be correct but I can't see nothing.

 

I've initialliy tried to generate a 1 khz sinusoidal form using a MCLK of 10khz and then different output and master frequency but I can't see nothing.

 

Now I'm starting to think that the AD5932 might be broken, is there a method to know if it still works without writing in the registers? Also can some of you give me a working code (either in c or in assembly) so I can try with that?

 

Thank you for your help.

Luca
