Help with Humidity measurements

Other Parts Discussed in Thread: HDC1080

Hello, I'm new to this forum (and new to HDC1080)..

I implemented a very simple program on that shoulld read both temp and humid...

The configuration register is initialised with 4096 (Bit 12), in order to read both values in sequence...

The reading of the values is approximately 20 msec. after the pointer to register 0 writing   (conversion start)..

The values that i read are correct and coherent for the temperature, but Humidity is way too low, it's raughly a half ot the value measured with a referecce hygrometer...

If i put my habd around the device it's humidity register raises up to over 0x8000 + , but if I leave it alone, it stays arounr 0x3F00  while I was expecting it to be greater than 0x6000  

I really can't find what I did wrong...

Regards
