Making Music with the FreeSoC2
Nick Poole 
Introduction
The FreeSoC2 is an excellent platform for playing with the capabilities of Cypress PSoC devices. I had never touched a PSoC before this project, so I wasn't sure exactly what I was getting into. Turns out, they're a pleasure to work with. Whenever I get a chance to play with a new technology, I like to build a simple musical instrument. Why? Because even the most basic keyboard synthesizer incorporates important concepts like pushbutton input and output, signal generation, signal switching and timing. Building this keyboard gave me a pretty good window into the FreeSoC2 and helped me get a hang of using the PSoC Creator software.
