Hi Don,

You say you want to make a "low frequency sinewave generator". Which frequencies are we talking about(highest)? Is it supposed to do anything else than produce this sinewave? How do you intend to control it? Which pic are you planning to use?

I'm asking all theese questions cause i know a way to do this(DDS or NCO), but im not sure it fits your application. I have it woking with 8 bit resolution, i'll see if it can be expanded to 10 or 12 bits. The sin part is a lookuptable, the "DDSengine" is assembler.
