 * @details Sample main program for MAX31723/MAX31722
 * The prints are sent to the terminal window (9600, 8n1).
 * The program configures the SPI buss and then it performs
 * 5 one shot readings.
 * The program then blinks the green LED.
 * 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.
