Data logging starts if a valid switch for enabling is selected (also when scrolling to the wanted position.
I would prefer the logging to be disabled as long as configuration is not finished.

I get no valid results when logging. These are the observations I have made so far:

- Sometimes "empty" lines (with invalid values, esp. timers=0) appear without changing any inputs
- often the converting to CSV stops with a message like "Cannot handle API version 0xe7" (with various versions 0x2b, 0xb8, 0x71...)
- often I have only a few or even one line in the csv output (can be an impact of the previous)
- I have chosen (with others) the rtclock, but it only appeared in the header line when I choose "All" (also no data from the clock logged).

EDIT: Forgot to tell that I use emu_devo12-v3.0.0-9caabf.

rbe, I think all your problems are because I had altered the way gps was displayed and didn't update the converter accordingly. Those should be fixed. If not, send me your datalog.bin

I'm not quite sure what you mean by datalogging begins before you are finished. You cannot setup the switches while the datalogger is running. There is the potential (say when moving from None to 'THR' to capture some spurious events. That is what the reset button is for :)
I could add a 'Save' / 'Cancel' button and cache all changes. I didn't think it was worthwhile, but it isn't too difficult.

I will test again later.

Logging while changing: I have seen the free bytes going down when I move through the switches - some of them were active (like one of GEAR0/1). Because the output was not what I expected I can not say if something useful was logged at this time or not.
To clarify: I spoke about changing the enable-switch, not the data sources.

I will make it so that the 1st capture occurs at current time + <x> each time the enable is changed. That gives you time to set it to a useful value. I think X of around 3 to 5 seconds is probably reasonable.

I have tested it shortly on my Devo12 and everything looks fine as far as I have seen. Some jumps in the data, but a correct datalog.bin and enough data inside:

Strange: jump in timer1 (17-12-19, 5 lines with 20; could be hanging while USB active...no, no more lines after a few minutes), values of 100/156 for GEAR0/1 (expected -100/+100 - ah: 156=256-100!! - unusual output...)

It looks like the last sample when the enable changes is bad, otherwise the data looks ok. As you noted, bytes values are currently unsigned and should be signed. I'll need to work on each of the others to show the data properly

I've updated the csv script to properly display values for all data types (I hope). The jumps in your data are i think caused by an off-by-one error in my code. I think I've fixed that too.
Let me know if you see more issues.

yes your datalog from yesterday is corrupt. that is disturbing, and I haven't made any changes that are likely to affect that so the bug is likely still there to be teased out. I haven't been able to replicate it on the simulator so far.

Devo12 crash. I'm pretty sure the datalog file filled up and now I can't get into the devo12. When I turn it on I only get the usb screen and windows tells me to format it... :(

Of course I have backups of everything, but this wouldn't be good at the field... ;)


AHHH crud... added a couple of models since my backup...

Anyway to get into the devo when it's in this state?

Has there been anyone working on an overall PC app?

It could include;
-usb flasher
-datalog display
-model editor/backup/organizer
-icon creator
-emu (select-able tx model)
-template organizer/creator for screens

I wish I had the skills to do such a thing.
