PIC18F452 and SHT75 |

Hi..
I am using the pic18f452 and the SHT75 humidity chip. I have used the code that has been pasted in the working example. My humidity is always -4.6 and my temperature is -39.9..
I have checked my wiring and it seems to be right. I have a 10K pull on the data line but not on the clock line. I have tried a pull down on the clock line and it makes no difference. I have tried a pull up on the clock line and again no difference!!!
I am using a 5V supply and have checked my voltage across my gnd and 5v and it is 5.04V..
Does anyone have any suggestions or ideas as to what is wrong??
Many thanks
