I've been a follower of the community for a while but have just now found an opportunity to post something. Forgive me in advance for the newbie question as I'm a ecologist/remote sensing guru first who also happens to operate a few drones for my work.
I am interested in hooking up additional sensors to the analog pins on an APM 2.5 and having them be displayed in Mission Planner. Namely, I would like to add one of these as a fuel level sensor in a large mapping plane:
It seems to be perfect, as it will provide a 0-5V signal. The only problem is that I can't figure out how to enable analog inputs in the code to get them to show up in MP. What I think I'm seeing is that I need to enable the sensor in one spot, maybe in the 1 second loop, and then have it sent over MAVLink using that routine.
Is that basically what I need to do? If so, any advice on how to go about it? I have to say I'm pretty wary of modifying firmware and compiling it myself, considering how important its job is.
