I have a custom sensor daughter board that outputs sensor messages via CANbus.  I was hoping to receive these messages on the Flight Core, but code examples are scarce.  Has anyone been able to invoke the CAN library from a standalone application and process incoming CAN messages, or put CAN messages onto the bus?

Hi Andrew,

We have other folks using it for controlling ESCs, let me try to see what I can find as far as examples, we don't have one in our repos.

PX4 itself has a UAVCAN implementation they've been working on that might be of help: https://dev.px4.io/master/en/uavcan/index.html

Thanks!
