TMP102: TMP102

Neeraj - 

from Ren's excellent suggestion - here is what that would look like (using coffee cup and LaunchPad (similar to your Arduino solution, but from TI, can use Energia, which is based on/related to Arduino - so the code below also works directly in there, too)

for your sketch, if you go this direction 

/////////////TMP117/////////address 0x48
digitalWrite(ledPin2, HIGH);
Wire.beginTransmission(72); // transmit to TMP117 device address 0x48
Wire.write(00); // pointer to register 0x00, start conversion
Wire.endTransmission(); // stop transmitting
delay(20); // delay set for 20mSec typical should be ~15.5mSec
Wire.requestFrom(72, 2, 1); // request 2 bytes from TMP117 device, register 0x00

while (Wire.available())
{
Wire.readBytes(iBuff_TMP, 2);
TMP_BYTES = (int16_t)iBuff_TMP[0] << 8 | iBuff_TMP[1]; // shift left
TMP_BYTES *= 0.007815;

Serial.print(",");

Serial.print(TMP_BYTES); // print out TMP116/TMP117 temp to terminal, in C
Serial.print(",");
}

/////////////TMP117/////////address 0x49
Wire.beginTransmission(73); // transmit to TMP117 device address 0x49
Wire.write(00); // pointer to register 0x00, start conversion
Wire.endTransmission(); // stop transmitting
delay(20); // delay set for 20mSec typical should be ~15.5mSec
Wire.requestFrom(73, 2, 1); // request 2 bytes from TMP117 device, register 0x00

while (Wire.available())
{
Wire.readBytes(iBuff_TMP, 2);
TMP_BYTES = (int16_t)iBuff_TMP[0] << 8 | iBuff_TMP[1]; // shift left
TMP_BYTES *= 0.007815;
Serial.println(TMP_BYTES); // print out TMP116/TMP117 temp to terminal, in C
// Serial.print(",");
