I am in the process of 'implementing' a pic in two private projects that I am busy with; One of them is an intelligent fan controller ; I have been experimenting with software based PWM, and am waiting for a 1-wire temperature sensor that I ordered to arrive so I can start playing with the 1-wire bus & protocol. The second project is actually a school project. I am supposed to design a oscillator that can generate a *perfect* sine from about 20Hz - 20 Khz, but I kind really got my self excited and decided to embark on an adventure with a DDS (AD9834). I am thinking of implementing a nice LCD with frequency counter and some *menu* options on it as well... All in the name of science of course!
