FPGA Code Example for interfacing to AD9910

Hi all

 

I was wondering if somebody has some VHDL example code to an FPGA for the SPI communication with an AD9910?

 

I need to initialize the DDS and then later control the DRG. I am using the evaluation board.

If you have code for the DRG control, that is also appreciated.

 

I know that I need to control all digital inputs, but does that include the parallel inputs, F[1:] and TxEnable?

 

I had a VHDL programming class 5 years ago, so I don't remember much. So, all help, tips and trick are also welcomed.

 

Thanks.
