+UART Configuration (It is necessary for see the results, we suggest to use TeraTerm on PC)  
+    Baud Rate:    9600 
+    Data Bit:     8
+    Parity:       NONE
+    Stop Bit:     1
+    Flow Control: NONE
+    
+This SW is ready to use on the NUCLEO-F334R8.
+Connect to the NUCLEO-F334R8 the DS18B20 sensor (see the schematic below).
+The temperature sampling time is 1 sec.
