Has anyone ever tried DDS with a picaxe? I'm working on more parts of my picaxe winradio type device, and am thinking of using an 18x in a DDS setup to make a CW filter.
Origionally I was only going to output a wide ~15khz signal (like 0-14khz) and dump it into a soundcard, using software to analyze, monitor, and filter it, but I've gotten bit by the "stand alone" bug.
So I really only need a 10khz at most, probably more like 5khz and retune to move things around where needed. I'm going to (hopefully) heterodyne the AF signal and pass it to a ~500hz crystal filter.
Any ideas/comments/flames?
