* @brief Sample main program for MAX30205

*
* @details Sample main program for MAX30205.
* The prints are sent to the terminal window (9600, 8n1).
* The program initially flashes yellow once, then it
* blinks green if it's able to communicate with
* the MAX30205, otherwise, it blinks red.
* The temperature is read out every half second.
* To run the program, drag and drop the .bin file into the 
* DAPLINK folder. After it finishes flashing, cycle the power or 
* reset the Pegasus after flashing by pressing the button on
* the Pegasus next to the battery connector or the button
* on the MAXREFDES100HDK.
