Hi all,

I have been assembling and building a quad since a few months back and using resources from DIY Drones and the Arducopter project. Have a working and flying (not very stable) quad right now! Many thanks to the Dev team!

My question:

If I want to add other types of analog sensors (ultrasonic or IR), I understand that I can connect to the free analog expansion ports (4 to 7) and use analogRead(AN4) or analogRead(58) to read them. (Not using 1 to 3 because they are connected to voltage dividers now)

But if I would like to add more than 4 analog sensors, can I connect them to AN8 to AN16? At the moment, it says in one of the tabs of the ACM code, "defines.h" that these ports are not connected anywhere. Does "Not Connected" means these ports can't be used?

Please kindly help me if anyone knows about this! Thanks!
