RE: [Mmcdtools-discuss] New log format

[Shawn P. <spo...@ex...>]

What is FSCount?
Why Decimal?  Why not do a printf-style %0.2f or similar format string?
I don't think I understand Interpolate.  Is this a display feature or
something else?
 
Also, is it really necessary to have backwards compatibility?  I mean,
it'd be nice, but if it really limits us, I say tell everyone to
upgrade.  Why would we want them to run old versions, when the same Palm
can run the latest?

Subject: [Mmcdtools-discuss] New log format
 
Reworking structs inside MMCd to simplify adding new sensor types.
 
Each sensor will include:
Short Tag
Long Tag
Units
HWChan     (ECU / expansion register)
FSCount     (255, 1023, 8191 etc)
Decimal     (number of digits to display)
Interpolate (0 if no interpolation, otherwise ID of interpolation table)
Scale
Offset
GrMin     
GrMax
This will eliminate a fair amount of redundant scaling code and simplify
adding new sensors. Same struct will be prepended to beginning of each
log to elminate hard coding of scaling info in MMCdTools.
 
Plan of attack on MMCdTools (to maintain backward compatibility) is to
detect "headerless log files" and use a default header structure.
 
Design decision on MMCd logger that I am still wrestling with is whether
to add support for > 32 active sensors or just allow up to 32 sensors to
be selected from a larger pallet.
