I should have said AD9832. But that was just an example
that would work. I may choose a different one for whatever
reason.
Regarding the Arduino board: that is what I would call
a "daughter" board, which I can't have. Is the Arduino
board open source, so that I can just copy the schematic
of it to my own board? Is the Arduino software also
open source?

I think maybe you might have meant the AD9835 ?
Anyway, there are plenty of code examples out there, do you have a
processor in mind or are you free to use whatever is suggested?

I need a very simple controller to tune a DDS with up/down
switches (imagine setting the time on a clock). A DDS
chip, such as an AD9836 would go on a PC board and a couple
of pushbuttons would tell the controller to tune up or
down.
Before reinventing this wheel, I thought I would see if
anyone knows of a similar solution that can be leveraged.
What I would like is both hardware and software, where
the software could be edited to accommodate the up/down
buttons. A last resort would be to write software from
scratch. My software skills are extremely limited.
Cutting and pasting code might work for me.
I need to be able to embed this onto an existing PC board.
I can't use a preexisting "daughter" card, other than
to copy the design of the card.
