How would one decode a TMP36 temperature sensor's reading as an input in ARM assembly language?

Question

I am working wiht a partner on a project and we are trying to make sure we can read a temperature sensor as an input to find the average value of the temperature over the span of around 10 seconds. We just are unsure of how to store the value of the temperature sensor in a register. Any help is greatly appreciated.

We have tried to find answere online but have only encountered one type of temperature sensor and it seemed to be a daunting task saying we needed to create a "bare metal environment" WE have the functions of the code essentially written we just need to get the input in order to use said functions.
