The PIC has no DAC, but you can make your own R-2R network easily enough, even if you can't get a DAC chip at short notice (circuit diagrams available everywhere).

Thanks guys

Actually many PICs now have a very course 4bit DAC

News to me - which PIC are you talking about ?

The ones with a comparator voltage reference module perhaps?

Yes, but it's not much use for plotting a sinewave with!

It's got 16 steps and a high & low mode, crude but it's there.
