External INS & airspeed sensor hookup - VOXL 2 mini
-
We are looking to hook up a VectorNAV VN300 external INS and an MS5525DSO airspeed sensor to a VOXL 2 mini. The INS data needs to be sent to the FCU. Both sensors have drivers in px4 - however, I don't think the VectorNAV driver will function on the SLPI proc, so it can't be as simple as hooking it up to the GNSS uart & mag i2c pins in J19 (correct me if I'm wrong?).
I just wanted to ask if this configuration is at all possible, and what might need to be done on the apps proc to get it working. I understand there's an exposed uart port in J10 that I can probably use, but I'm worried about potential latency issues & not sure how the data should be piped over to the FCU.
Thank you!

@jonathankampia Correct, The VectorNAV needs to have the serial port implementation changed to support SLPI. That can either be done by modifying the code on our branch or going to mainline PX4 and modifying the implementation to use the platform independent Serial port abstraction.
