Hi Michael,

    I was looking over your program, and I have a suggestion for creating the 
Lm75temp variable.

mov {Lm75temp} , Lm75low    ' mov data into low byte

Rotate Lm75temp , right , 7    ' shift everything 7 bits

The extra shift was added to perform

    Dispval = Lm75value * 0.5

Your answer is now in Lm75temp.

I just thought I would show you a different way to do the same thing using 
less code.
