Continuing to work with the ICD2 (I have to say that so far I vastly prefer the Wisp628, but since I want to work with the ds3013 chips it appears that the ICD2 is required), I have come to the point where the documentation strongly suggests that I should get myself a dsPICDEM 28-pin starter demo board. I looked up the price, and the little bugger is fairly expensive (the ICD2 pretty much depleted the budget). But if I really need one, I can skip the prescription drugs for a couple of months, I suppose, and get one. Except that it is not clear just what it does. I have a perfectly good solderless breadboard that I have used in the past (with the 18F452 and the Wisp628) for developing circuits. What extra does the dsPICDEM give that is crucial? (I'm not criticizing it -- just cannot figure out why it is necessary).
