Hi,
I have started implementing a second voltage monitor in ArduPilot. The code is currently only implemented in ArduPlane and can be found at my fork at https://github.com/Xtreamer/ardupilot.
Support for the modified MavLink message SYS_STATUS has also been implemented in the Mission Planner software at:
github.com/Xtreamer/MissionPlanner
You can only set the parameters from “All parameters” at the moment, the battery tab contains no new info right now.
I have previously tried getting some input at diydrones, but have gotten very little response. Hopefully this is the right place!
My problem is that because I have changed the SYS_STATUS message definition every other software receiving that message will have to change their source. I don’t know the community well enough to coordinate something like that.
I have to add support for the aux battery monitoring in ArduCopter and ArduRover, which should be easy as most of the code is in the AP_BattMonitor library. But before I do that and start talking to more people it would be hear something from “someone in charge”.
