Hello All  
I want to read 4 sensors (Temperature, Speed in rpm, distance, and fuel level ) data on the CAN2 pin (CANH, CANL, Vi, GND) in Pixhwak and display this data on the ground station(Mission Planner). All sensors give an analog voltage so I read this voltage and calibrated their appropriate value.  
So how can I connect my controller CAN to pixhawk CAN?  
Can i see all sensor data in the mission planner?

Thank You.
