I've seen generating sine waves using PICs and other associated "complex" hardware in the archives. And can find a /couple/ web sites showing some oscillator and integrating amp sine generators but none seem too complete or tested. I'm curious how I could go about generating a (roughly) 0-5 Vpp sine wave, in the range of 1Hz or less... It doesn't have to be very accurate, just simple, and generate a periodic wave. I'm looking for something made from (fairly) basic components (op amps probably being the most complex), no 555 timers, etc, that's cheating! My engineering schooling is limited on the EE side (more digital) so I can't seem to come up with something that works! :) Thanks! nick@veys.com | www.veys.com/nick -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
