                  <p>The trickiest part when soldering a freeDSP CLASSIC by hand is the ADAU1701, which comes in an SMD QFP-44 packaging. Ludwig made a video to show the soldering process (currently only in German language). However, this is definitely not recommended for soldering beginners! If you are in doubt of your skills better wait for a freeDSP kit with preassembled SMD parts or a populated board.</p>

                  <p> Das Ziel dieses Beispielprojektes ist es, die Kommunikation eines PSoCs mit dem freeDSP INSANITY zu erläutern. Dabei wird auf die Kommunikationsprotokolle SPI zurückgegriffen. Des Weiteren wird das allgemeine Vorgehen für die externe Steuerung des freeDSP mit dem PSoC erläutert. Die Funktionsweise der Kommunikation wird anhand eines praktischen Beispiels dargestellt. Dafür wird für eine E-Gitarre ein mittels eines kapazitiven Sliders gesteuertes Effektgerät mit einem Pitchshift (Vibrato) entwickelt.</p>
