Part Number: HDC1080

I had a HDC1080 EVM. I read that the back end of the evm can be broken off from the perforation and used as a standalone sensor on a micro-controller. I tried to interface it with the MSP430G2553. I have done the following with no avail:

1) the jumper on P1.6 has been removed(no interference of led with SCL line)

2) I have tried using pullup resistors on both the SCL and SDA lines. I have tried out with the standard 4.7k resistors and also with 10k resistors.

3) I always get a temperature value of -40 degree C and humidity of 0%, which means that the MSP is not able to get the readings through.

4) I am using the Wire library on Energia1.6.10E18 and I followed TI's tutorial video on how to implement HDC1080 on Arduino. Here's the link (
