Our project was completed within a fair degree of success. Despite the use of high-pass filters at both the input and output stages of the system, there was still a lot of static present with the signal. We think that the cause of it is that our code did not put the data back out to the DAC fast enough, and so the DAC output looked more like a stepped function than a smooth curve. This stepping would have contributed to the static in the output, but would have followed the actual output, so we still would have heard some element of the inteded output wave, which we did. The LCD/Nintento 8 combination worked mostly to our design. However, the big hang-up came when we tried to integrate our LCD/Nintendo code with the effects processing. Anytime a button is pushed, the code would hit a Software Exception in the effects code, which we were unable to resolve. Nevertheless, the two systems did work quite well independantly.
