The compass is showing the relative direction of an object that is being tracked. The direction finding equipment is sending the bearing to the db. I need to read the db and update the pointer to reflect the bearing that is in the db. Think of a compass on a smart phone as you turn the dial moves. that is what they want except with a few more options.
I dont know whee to start with this one?
