AD9914 for Arduino

Hi,

I want to write the AD9914 with the ARDUINO UNO and found very little on the net.

The one SW I found is attached as PDF and was compiled without errors, but I could not see anything on the Spectrum Analyzer.

Maybe you guys out there can give me some hints.

1) It does not say if I have to provide an external source as clock.

2) I tried to set the tuning word for 10 MHz CW but it seems not be equal to what the code says.

3) I used an external source of 25 MHz as REF_CLK input, maybe this is the problem ?

 

Many thanks in advance for all the Aduino fans out there in the net
