UART with Launchpad and CCS

Hello everyone!

I'm beginner with MPS430  and I want to make a serial communication in UART mode using my launchpad. My objective: Turn on/off three leds and reads one-wire temperature with DS18B20 one-wire thermometer. I don't know how to do it but I was reading the TI example for UART

Somebody could explain me in which manner I can use this piece of code to achieve my objective?
