But I want to use a DAC, and I don't have 4.7mH inductors.How about this:Store a lookup table in Memory, consisting of a some (?) values pre-calculatedLoop these values, with delay on each loop setting freq.i.e. a delay of 10usecs on each iteration will have a higher frequency than one with 100u secs.How many lookup values should I have?
Nevermind-- just realized that comes out to about 64KB! using floating point.
OK. so my 14-bit DAC should operate at max with a lookup table of 1024 values?
