Module dataflash 

ArduPilot DataFlash logs (.bin).

A DataFlash log describes its own messages: each FMT record gives a message type’s id, length, name, format characters and field labels; every other record is A3 95, its type’s id, and its fields packed end to end. One pass records where each type’s records start (crate::indexed) and reads the units and multipliers of FMTU, UNIT and MULT when the log has them; each type is then a table decoded from a map of the file, its columns typed by their format characters.

Every length is bounded: a record by its type’s length and the file’s end. A byte that does not start a record is passed over to the next A3 95 and counted.

looks_like

Whether head, the first bytes of a file, begins a DataFlash log: an FMT record that defines FMT itself.

notes

What the Notes tab says of the pass.
