It turns out each familyVersion has records of different sizes, including
the first one containing the settings. It may make more sense to split
summary and/or settings parsing into multiple familyVersion-specific functions.
Also it looks like the F0V4 humidifier settings are actually 60 Series
settings, and the "V2" settings are original System One settings, not
all fileVersion 2 machines.
"Support" in this instance means that it will quietly ignore the events, since there's really
nothing to import. But this means that parsing will correctly continue past the events, even
though so far they're the only events in a session. There are diagnostics to log if that
assumption turns out not to be correct.
Still trying to figure out timestamp event.
Other summary parsers will need review, since there was an initial
filter that was dropping sessions that began with event 5 or 6,
now commented out.
Based on the F0V23 loop and F0V6 switch statement, along with manual review of
several sample files to determine record length.
Split ParseHumidifierSettingF0V4 out from ParseSettingsF0V4.
These are events that are in the PRS1 files but which OSCAR doesn't know how to present:
- An F0V6 event with duration that looks like PB or LL but doesn't appear on any official reports
- The Auto-CPAP pressure to use at the beginning of a session
- A report of the snores detected at each pressure/EPAP/IPAP
- Apnea alarms on F3V6
Rather than bury the understanding in commented-out sections of the parser, these events
will now be parsed and added to the internal event stream, which allows them to be dumped
to YAML. Whenever OSCAR eventually supports these data, the importer will have ready
access to them.
Again, no change to external behavior.
This only affects the parser at this point, and the importer has been updated so that
there is no externally visible change to the imported data.
Eventually we'll need to figure out how to display the two differing kinds of
pressures, at which point we'll need to fix the importer to use the right channels,
instead of the inconsistent treatment now.
The next step will be to split parsing from mode interpretation, so that
we can at least accurately identify all of PRS1's modes. Then we can
work on mapping that to OSCAR's notion of modes, which probably then needs
to be augmented.
