I am trying to dive into the world of Pic's but have no idea where I might be able to look up some example code. I am interested in doing some very basic things and hope to one day be able to make an arppregiator.

thanks!

I have a (fairly old, but still usable) overview of basic PIC info on my website. It has gotten good responses from folks over the years:

The only difference now is that there are some excellent newer PICs to choose from. I've been having a lot of fun with the PIC16F690 which is cheap and very simple to use. Also, I highly recommend the PICKit3 programmer which is low cost and works very well.

In terms of doing synth stuff, there are so many possibilities. If you want to start by making some sound, you can make quite good digital oscillators. I've done a number of different configurations and would be pleased to offer some help based on what you'd like to do.

I think the most important part of getting into micros or any sort of "embedded" electronics is to understand the speed and capabilities of the system. Once you can get your head around what's possible in terms of timing, processing power, storage, etc. you'll start to imagine uses and potential projects that you never thought possible before! There is also nothing wrong with using more than 1 PIC in a circuit... treating it more like a custom chip than an actual computer. For $2 you can make some pretty impressive "special purpose" chips for your projects. Smile

Cheers!

I prefer the more-than-one-micro-per-circuit route myself!

although pics/avrs can make nice oscillators (using DDS), it consumes quite a bit of resources. especially if you're going for a nice smooth sine or triangle. doesn't leave much for LFOs, other oscillators, the brains, etc. however, remove the oscillator and a single pic/avr has more than enough power to do several LFOs, ADSRs, MIDI, brains, all at once. those other things don't require constant thinking every nanosecond like an oscillator does.
