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.

This SW is just for only one DS18B20
This SW is a derivative of:: https://developer.mbed.org/users/Sissors/code/DS1820_HelloWorld/
On the: https://developer.mbed.org/users/Sissors/code/DS1820_HelloWorld/ there is a multi sensor (DS18B20) example.
