This is a checkpoint where Tiva, Stellaris and Cygwin builds all work. The Stellaris build (IAR 5.4) turns the motor, however, Tiva (built with IAR 6.4) currently only runs the idle task which flashes the LED. Note that a full rebuild is required when switching between the IAR builds since the object files are common between builds.
Several things to note: Added an interrupt acknowledgement for the timer. This isn't in the Stellaris build so I'm puzzled why this works. Also, reduced the stack size on the idle task to 32 bytes. Any lower and the task fails.
Started modifying the GPIO lines for the Tiva chip since they're different from Stellaris. I had to use different ports because of the board layout.
Modified the Python transfer code so it doesn't print <OK> after every line is transferred. It still prints the transferred line, just not the <OK>, which was becoming annoying.
