I have already tried this code but I do not get any value. But yes I received strMsg string in TeraTerm Window but It does not contain any value of sensor reading.

Did you add a 5k resistor to signal pin and connect other side of the resistor the + pin or J5 pin 7 ? Also the signal pin (S) connects to P3 pin 0 on your pioneer board and the +5V pin + connects to J5 Pin 7 of the pioneer board and - or ground connects to J5 pin 3. You did say that you are getting the channel message on your terminal program. I usually jumper the UART out pins to P12 pin 6 and P12 Pin 7. See attached picture. That way I can use the USB kitprog for a terminal using my favorite program PUTTY.

Actually, I put 4.7K resistor between Vdd and Signal Pin. I already connect UART Connection like this.And I am getting String at output side but it does not contain Temperature Value. I have check this program but in onewire.c it returns BusPresence=0;
So i come to know that my sensor is not detected. what to do next?

Port 3 Pin0 is not soldered so i use pore 1 pin 2. So is it ok? I have changed that accordingly in schematics.

Thank you so much for help.
It is done. Actually everything was right in my coding but there is problem with the heap size of memory location that's why float values were not shown in my output string.
