+*
+* @details Sample main program for MAX30101.
+* The prints are sent to the terminal window (9600, 8n1).
+* The program sets the GPIOs to 1.8V and the program
+* blinks green if it's able to communicate with
+* the MAX30101, otherwise, it blinks red.
+* 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.
