* @brief Sample main program for MAX6605
* @version 1.0000.0000
*
* @details Sample main program for MAX6605
* The MAX6605 precision, low-power, analog output temperature 
* sensor is available in a 5-pin SC70 (0.65 mm pitch)package.
* The device has a +2.7V to +5.5V supply voltage range
* and 10µA supply current over the -55°C to +125°C temperature range.
* For the -40°C to +105°C temperature range, the supply voltage can go as low as +2.4V.
* Supply Current: 10µA
* Supply voltage: 2.7V to 5.5V
* Accuracy : ±0.75°C 25°C
*            ±3.00°C 0.0°C to 70°C
*            ±3.80°C -20°C to 85°C
*            ±5.00°C -40°C to 100°C
*            ±5.80°C -55°C to 125°C
*
* The prints are sent to the terminal window (9600, 8n1).
* The program sets the GPIOs to 3.3V 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.
