USB2000 and some Flame S error at initialization due to fpga firmware version register check about python-seabreeze HOT 4 OPEN

Interestingly I am also seeing this from one of my FlameS sectrometers. Others are operating fine (ie are fixed by https://github.com/ap--/python-seabreeze/issues/97#issuecomment-674567912)

from python-seabreeze.

Hi @dbhatman

Thanks for the report!

I don't think your USB2000 is a nonplus version. That code path is just run for the USB2000+ and FlameS if I'm not mistaken.

Can you please report the vendor and product id of the USB spectrometer?

Regarding the FlameS:
Could you try running your test code with the optimize flag so that assert statements are skipped?

python -O myscript.py

It seems your flame S is on major firmware version 3. It's possible that they changed the return code in those revisions.

And could you try to figure out what version of seabreeze broke the USB2000-nonplus for you?
If you could just pip install older versions to see when it broke, that would be super helpful.

Cheers,

Hi all,

Been running into the same issue with a USB2000+ (the AssertionError) and found that the most recent version where I didn't get this error is version 1.2.0.

from python-seabreeze.

Hi @jlball,

Thank you for checking the versions and reporting back. Could you provide the error message when the assertion error is raised using the newest seabreeze version, and could you try running your test code with python -O yourtestscript.py to disable assertions.

If you can confirm that the code runs with assertions disabled, I can release a new version without the check.

Thanks,
Andreas
