airmailed Posted March 30, 2005 Report Posted March 30, 2005 http://www.edn.com/article/CA313057.htmlhi, i was reading this article about using a pic to generate noise and it got me wondering if a wavetable generated by a pic could also be used as an oscillator? (if the wavetable output could be connected to a dac or directly to an audio output?) just curious ;-) Quote
AndrewMartens Posted March 30, 2005 Report Posted March 30, 2005 Short answer: yes, with a but.Long answer: TK did some experimentation a long time ago, and I've tossed around some ideas. It can be done, but it depends on whether you want to just do a square wave, or a whole wavetable, etc. There are lots of factors to take into account. I mentioned part of my plan (long-term, not likely to be finished this year) here: http://69.56.171.55/~midibox/forum/index.php?topic=3713.0Discussed a few of the details with TK in the middle of this thread: http://69.56.171.55/~midibox/forum/index.php?topic=3687.15 Quote
moebius Posted March 30, 2005 Report Posted March 30, 2005 There's pretty much action in the SDIY mailing list at the moment with microcontroller based digital oscillators..It's mostly phase accumulator stuff and done with AVR's.. (only one guy is planning one with a PIC) but anyway, couple of links for inspiration:http://www.jarek.synth.net/http://krue.net/dco4/Bye, Moebius Quote
