Hi Mr. Taylor,

I am goping to prepare an home made weather station : this will be an hobby project for my small radio ham station.
I have seen the pressure transducer calculator you have post to me: it is very interesting.
I would like to use the PIC 10 Bit ADC instead of using an additional 12 bit ADC.
I have considered that my home is at about 1050 ft above the mean sea level and the baro pressure will never change so widely. I have in mind to put the PIC ADC " -REF " to 3.75 Vdc and the ADC " +REF" to 5Vdc.
The 3.75 Vdc is about 938 mB of presssure that has never been observed here in the years.
In this case I will use 10 bit to read the voltage output from 3.75Vdc to 5Vdc.
What do you think about that ? Do you recomand this solution ?
If it will be Ok, what will be the final PICbasic code ?
Thanks a lot for the interest.
