I see there is parameters for up to 3 rangefinders and I would like to consider using 2 analogue rangefinders / echo sounders for a task. Was this carried over to ArduSub project or are they remains from the ArduCopter code?
What is the parameter RNGFND1_PIN: Rangefinder pin referring to physically? It states Airspeed ports. Which pins would need to have the analogue signals (0-5v) feed into them?, on which connectors?, on the Pixhawk in order to be able to handle multiple simultaneously? Is this even possible?
Thanks for any advice.
