Hi all:
I am in the process of designing a project for school. This project
requires a GPS sensor and a barometric pressure sensor to determine
position in space. I have not much knowledge about sensors yet but I am

Hello,
I have limited experience with microcontrollers, all with freescale HC12
and HCS12 systems. I have dealt with 0-5V sensors through ADC before, too.
