Hello.
I have a question about UAVCAN, so I leave a question.
Parameters related to UAVCAN include UAVCAN_ENABLE and UAVCAN_SUB_BAT parameters.
If I set both parameters to work and only get UAVCAN data through the CAN port, can I read the battery data from the px4 without any extra programming work?
Thank you.
Yes, you can. If you enable both parameters and if you use a device that provides battery status messages over UAVCAN you will be able to see battery status in PX4.
p.s. Maybe you will also need to set BAT1_SOURCE to external (meaning is not using the board’s ADC but data from an external device).
FYI DroneCAN (which is old UAVCAN0) setup is here: DroneCAN | PX4 User Guide
It doesn’t cover battery specifically, but does note the need for the UAVCAN_SUB_BAT parameter to be set.
