I recently got hold of a dsPICDEM 1.1 board to help me learn about the dsPIC architecture. At the moment, the learning curve is a bit steep (to put it mildly!) and I wonder has anyone on the list managed to do any audio processing using the onboard SI3000 codec?, using the C30 compiler; if so, I'd really welcome some pointers as to how to simply read an audio stream from the codec's microphone input, and write it back out to the speaker output. (BTW, I have got a C30 "blink an LED program" to work on the dsPICDEM 1.1!)
