I'll check this out but in the mean time I added a simple data logger to
the fly-by-wire board since it only required the addition of 1 inexpensive
part. Data logging time is limited to 74 minutes at a sample rate of
once every 2 seconds. This should be plenty for analyzing
cooling & performance issues.
It ain't over yet since this only stores the raw sensor data.
As Rusty points out, I (or a volunteer with some programming/EXCEL chops?) need
to write the program to download the data and an EXCEL spreadsheet to
display it in a nice chart.
BTW, Congrats Buly! Now, give us more details on that
needed cooling tune-up : )

programmers?)
Subject: [FlyRotary] Re: Possible data-logging solution?
Interesting Phil. I just bought a
serial data logger for my Dynon DS180 (EFIS and EMS). I just received
the Dynon, and data logger, so I haven't had time to try anything with
them, but this setup has promise for Tracy's stuff as
well.
At the moment, the unit only logs one
of the two serial channels, but in the next version of software, it
will log both channels. It uses SD or MMC memory cards, so you can
take them home to read them. The OEM version has this
card slot available on the bottom of the board, where the boxed
version is enclosed. I'm told you can use any branded memory, so you
don't have to buy theirs. I got the 128 mb version, since they seem
to screw you on the memory cost, and I can buy larger cards much
cheaper from other vendors.
They don't use the FAT file system, so
you need their "reader" program to read the memory card on a PC, or you can
use a laptop and download the data via X-modem. Once I get the
data, the next problem will be figuring out what to do with it. I guess
I'll be learning more about Excel than I cared to know.
Cheers,
Rusty (one week until my "sentence" in
Cleveland starts)
