USB power/GUI mode of evaluation board
The second mode of operation of the Temperature sensor board uses GUI through a USB
connection. In this mode if GUI is not connected, then the board functions as a mass
storage device and appears as a removable drive on computer. To use the board in
temperature sensor mode we connect it to the computer using the USB cable and
communicate with GUI using the USB communication protocol. GUI is used to configure the
temperature sensor registers and to explore all the features of the temperature sensor.
