Static calibration process crash

Postby qavAQ37 » Wed Feb 12, 2014 8:41 pm

Hi,

By following the tutorial, I have done a static file for calibrating AQ6 sensors between -20°C and 60°C :
https://www.dropbox.com/sh/lhjxf81h78vogp1/WDvedFqTTY#/
as you can see, warm time is approximately 9 hours and file size 2.2GB
cal program crash when i try to calibrate with this file, no problem so far with other smaller files.
Does anybody have encountered this problem with this kind of static calibration ?

Custom CAN shield mount on F.C and ready to test on QAV540G setup, now i m stuck with calibration .... :?
Thanks for help
Xavier

Hi Xavier

Maybe you could do the process within +- an hour. That usually works after cutting a bit start and end where jitters occured while connecting/disconnecting ect.

Cheers

Hi Xavier,

9 hours :shock: I don't know anything about the internals of cal/sim programs, but I believe they read all the data into memory first. That's a lot of RAM/swap space... even if the code can handle all that data, one corrupt memory register could throw it all off (or at least I could imagine that happening pretty easily :geek: ).

Can you heat it up a bit faster? :)

1 hour, max 1,5h is a enough time to increse temp to +45-50 deg C in foamed box
Try it. Bigger file isn't needed.

Too big files makes definitive problems.
So, you can cut your file, to the relevant part, and try again.
