Stellaris as a tool

The best example of Stellaris as a tool is as a logic analyzer see here.. http://www.sodnpoo.com/posts.xml/variable_sample_rate_stellaris_logic_analyser.xml

Currently I am working with the ESP8266 modules and I wanted to see what was being transmitted and received over  the serial interface without cluttering my code with debug.

Stellaris is perfect.
