Has anybody here attempted to use a pic to control a dds chip (and
wrote the software himself)?


Wander on over to
http://www.amqrp.org/elmer160/board/index.html
and click the 'Test Software.ZIP' link. In the source is just a few lines
to control the DDS. That particular program does everything but the kitchen
sink, and the DDS part is just a tiny fraction. The advantage here is that
the DDS code is split out, and you can see just how simple it really is.

Then, click on the 'VFO Software.ZIP' link. That piece of code for the same
hardware is really focused on the VFO capability, and has all sorts of
features.

I think Craig still has the original code still in there from WB2V that
allows you to calibrate your oscillator against WWV. If not, the original
'SigGen' code does. Google for SigGen, WB2V, WB9KZY or AA0ZZ.
