    Agreed, and paying $15 for a DDS IC, that I can (hopefully) get a $1 PIC to fulfill my (modest) needs means I am indeed trying to use the right tool for the job - i wouldn't use a rotavator to dig over my garden when for my tiny bit of soil a spade is just fine (while a rotavator clearly turns soil over, I'd say it wasn't the right tool for the job in that instance)

    Again, I don't need to generate 20khz (that's 4 times higher than I need), I don't need 12 bits resolution (that's about 5 or 6 bits more than I need).

    But more importantly, I don't learn a thing if I go & buy a DDS IC (& at the end of the day, isn't that why most of us do this type of stuff?)
