Phong,
I don't believe there are any examples of code for the TMP006 interfaced to a stellaris readily available on the forum, however the process should be very similar to the MSP430 code that was posted here, or there is also example code in this thread: http://e2e.ti.com/support/other_analog/temperature_sensors/f/243/t/193151.aspx for the launchpad booster pack for the TMP006.
