Since the time it was first featured on MAKE, Steve Chapman has continued to develop his iPod breakout dock. The dock provides all of the possible connections that could be made through the 30-pin connector. Of interest is the iPod’s serial interface. I had seen a break down of the control codes before, but Steve has taken the time to develop a serial application that he can use to test the different commands. Now that he knows a little more about the interface he’s started programming a microcontroller to use it.
