The test harness! When one lacks more sophisticated gear, this is a great way to get started and have a chance at success. BTW: I love Propeller chips for this purpose! They are multiprocessors in both the parallel and concurrent sense and that makes them quite useful! One can build up simple scopes, logic analyzers, signal generators, and other useful tools and use the chip to both display output, measure and more.
