Frequency axis on Analyzer view shows infinite frequency about blackbox-log-viewer HOT 16 OPEN

I've seen a couple of comments on the forums with users asking what the frequencies are. The axis label seems to have taken over from the scale labels in the display.
I can't find the word infinite in the code.

Did you try looking for "infinity"?

Edit: NVM that doesn't come up either.

I did look for infinity as well using github search and there were no hits in the code. I hope @DzikuVx has a look at this problem. I can see lots of users having problems with it. The graphs look OK, it's just the labelling.

@spatzengr If you find some time. Can you please take a look at this issue. Possibly caused by #86

from blackbox-log-viewer.

@rts18 , yes. I noticed the same issue but didn't associate it with #86 , but I can investigate to see wsup.

I'm having the same issue. Is there a fix yet for this? I'm having issues tunning my filters. or is there a work around?

My current work around is to use the last version of BBV

from blackbox-log-viewer.

I gather it can be caused by missing entries in the BB Recording. Try reducing the amount of data collected. Some of the FC's are at the limit of what their design can handle.

I don't think that is the problem here (or not the entire problem)

For one thing, BBV5 can render the FFT with scale without a problem from the same dataset that doesn't work in BBV7.

Have you been able to demonstrate a working FFT scale in BBV7?

from blackbox-log-viewer.

You need to verify that the log has no missing entries. There is an excellent set of BlackBox Tools written by Jonathan Hudson on Github, which can verify this. He can be contacted on our Discord Forum as @stronnag .

Can you demonstrate that BBV7 works with any logs? Why does the BBV5 work with the logs and BBV7 doesn't?

BTW, I had already tried on multiple quads and log rates. One of the quads I switched to BF, and it didn't seem to have any log issues (BF BBV worked correctly.) Also, one of the FC was using SD card for logs and the other was using a 16MB flash chip.

I think BBv5 is probably less fussy and skips over problems. BBv7 might be doing something new. Ask @stronnag on Discord. Sent from my Galaxy

Do you have any to examples of a successful frequency plot?

from blackbox-log-viewer.

These were produced more than a year ago and show vibration before and after replacing a problem motor.

Unfortunately I did not record the version of BB explorer I used but it was 2023/24. It wasn't the current one!

What FC generated the BB recording, which caused the problem?

@aviphysics I can confirm your findings. I see infinity on every copter or plane log I record, when viewed with blackbox explorer 7.
However all logs render the FFT scale consistently with BBE 5.
