I’m a new developer trying to implement new/custom flight modes. I’ve gone through most of the ArduPilot Dev documentation, however I still don’t understand how and where the apm.pdef.xml and apm.pdef.json files come into play in the grand scheme of things.
Specifically, it seems like the json and xml files define parameters along with descriptions and values. Is this information only ingested by the GCS software? Is it used in logging? Do I need to update these files if I add a new flight mode?
Thanks in advanced.
