00065 * @details Sample main program for MAX30205.
00066 * The prints are sent to the terminal window (9600, 8n1).
00067 * The program initially flashes yellow once, then it
00068 * blinks green if it's able to communicate with
00069 * the MAX30205, otherwise, it blinks red.
00070 * The temperature is read out every half second.
00071 * To run the program, drag and drop the .bin file into the 
00072 * DAPLINK folder. After it finishes flashing, cycle the power or 
00073 * reset the Pegasus after flashing by pressing the button on
00074 * the Pegasus next to the battery connector or the button
00075 * on the MAXREFDES100HDK.
