Oh I&#x27;ve done this too on my TI Launchpad projects.  Supposedly there is a way to attach a debugger, but I haven&#x27;t figured out how to do that yet.  I turned the LED on and used longer and shorter &quot;on&quot; times to differentiate between 1&#x27;s and 0&#x27;s.  It was fun, but the feedback loop was very slow.
