Zero Wire Debugging Using Inductive Technology

摘要

To reduce development costs, embedded systems designers are increasingly drawn to micro controllers with low pin counts. The downside of this trend is that the overhead associated with adding just one debug pin increases dramatically. Designers ought to be concerned because they have come to rely on these on-chip debug pins to do their in-system debugging. An innovative debug technology being proposed here aims to address some of these concerns. Zero Wire Debugging, as it's known, is a up-and-coming technology that applies the principle of inductive coupling to create a debug interface. It requires no extra debug pins and no extra circuitry on the application hardware side.
