Overview
When powering up the Out-of-Box demo, the board performs an initial temperature calibration and
illuminates RGB LED2 in a green color. Try to heat the temperature sensor U1 by blowing hot air on it to
see if you can get LED2 to turn red or using a compressed air can to blow cold air onto the sensor to see
LED2 turn blue. LED2 indicates the relative difference between the current temperature and the calibrated
measurement.
Press button S1 to recalibrate the temperature to the most recent measurement and send a UART
message (at 9600 baud) containing the new calibrated temperature through the backchannel UART. Press
button S2 at any time to send a UART message containing the current ambient temperature measurement
in Celsius.

main.c
The Blink LED main function
Library: Driverlib
The main code uses the MSP430 Driver Library to halt the watchdog timer and to configure and toggle the
P1.0 GPIO pin connected to the LED inside a software loop.
