I found some more demos from Altera that look like they're made specifically for the audio chip and D5M camera and are also usable so I'm going to test them first. If they work I'll go back to debugging my core since I'd like a generalized version. Thanks for the input I'll get you some more information. Also, I do have an oscilloscope and I'll take some readings with that as well. Thanks!
