phonemacro 0:f205abc96ff9 61 * The prints are sent to the terminal window (9600, 8n1).
phonemacro 0:f205abc96ff9 62 * The program initially flashes yellow once, then it
phonemacro 0:f205abc96ff9 63 * blinks green if it's able to communicate with
phonemacro 0:f205abc96ff9 64 * the MAX30205, otherwise, it blinks red.
phonemacro 0:f205abc96ff9 65 * The temperature is read out every half second.
phonemacro 0:f205abc96ff9 66 * To run the program, drag and drop the .bin file into the
phonemacro 0:f205abc96ff9 67 * DAPLINK folder. After it finishes flashing, cycle the power or
phonemacro 0:f205abc96ff9 68 * reset the Pegasus after flashing by pressing the button on
phonemacro 0:f205abc96ff9 69 * the Pegasus next to the battery connector or the button
phonemacro 0:f205abc96ff9 70 * on the MAXREFDES100HDK.
