MC9S08QE32 I2C problem with Tmp112

Hi,

I'm tring to read temperature from Tmp112 sensor connected to my MC9S08QE32 via I2C bus.

 

I've generated the code with Processor Expert, but I never receive the ack condition, so I always read ZERO.

 

Is possible to see some I2C (Processor Expert) working code? Just as example.

 

Thank you.
