+* @details Sample main program for DS7505
+* The prints are sent to the terminal window (9600, 8n1).
+* The program sets the GPIOs to 1.8V and the program
+* configures the chip and reads temperatures.
+* 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 (MAX32630FTHR) after flashing by pressing the button on
+* the Pegasus next to the battery connector or the button
+* on the MAXREFDES100HDK.
