GENERIC SUPPORT FOR PARSING INTO XDATA
.. Generically parse FIT file messages into XDATA. The current
implementation does this for session, lap and totals messages
but could very easily be extended to any other message type
.. Generic parsing uses metadata rather than hard coding the
message and field types and so on
.. The FIT metadata (FITmetadata.json) has been expanded to
include definitions of message types and all the standard
fields within the message types
.. The existing hard-coded parsing remains to extract data
and apply directly to ridefile samples and metadata. The
generic parser simply adds additional tabs on the data
view as XDATA so users can access it.
CODE REFACTORING, COMMENTS AND BUG FIXES
.. At some point the code needs to be refactored as it is
janky and needs to align with the rest of the codebase
.. Includes a mild refactor renaming some of the classes/structs
and variables to reflect what they actually are, for example:
FitFileReadState -> FitFileParser
FitDefinition -> FitMessage
.. Added lots of code comments and re-organised the code
into clear sections to help navigate what is a very
cumbersome source file, this breaks git blame history
but is worth the loss (you can checkout an earlier commit
to do a full blame)
.. Changed debugging levels to be more helpful
.. Generally I did not change any code, but there were a
couple of serious bugs that needed to be corrected:
Field definitions gets the type wrong in a couple of
places since the type is stored in the low 4 bits:
type = value & 0x1F
The decodeDeveloperFieldDescription function did not
check for NA_VALUEs for scale, offset, native field
.. For less serious bugs I added FIXME comments throughout the code
Fixes#4416
.. clarify how to make updates in the README
.. replace the fit_example.h from the current SDK
.. added Garmin devices not yet supported in the SDK to
the nongarmin.json file
.. updated the makefile to use python3 and update when
the python program is changed.
