Might I suggest that you back up in your process just a bit and practice/learn how to convert and display various types of numbers in general before trying to convert and display a result from a temperature sensor.
You don't seem to understand that the references to the earlier posts that we are giving you have the some of the information and answers you need to finish your project, DIG is on of those, if not the only one you'll need to convert your data from the binary format to the ASCII format (along with a bit of simple addition) to send to your display subroutine.
We do not have the hardware you have. We do not have the same 'vision' of the final project that you have, therefore, I think it is relatively unreasonable to ask others to write code FOR you, since that code that is written probably won't work for YOUR particular setup in the end. One thing that DOES work almost everytime though is trying to give a person the building blocks to start somewhere and end up somewhere else...
