Flame-S in version 2.4.0 pyseabreeze and trigger mode

[waldowda]

spectrometer and system information

• model: Flame-S / USB2000PLUS
• operating system: Win10 64bit
• python version: 3.8.16
• python-seabreeze version: 2.4.0
• installed-via: pip

current problem

Update on trigger issues on Flame-S moving to current release.

Flame-S (USB200PLUS) is recognized when using cseabreeze backend but not when using pyseabreeze backend. When cseabreeze is used, trigger mode 4 is not allowed.

When using python 3.8.10, seabreeze version 1.3.0, and pyseabreeze, trigger mode 4 is allowed. I can continue using 1.3.0 although it might be best in the longer term to stay current with the latest stable release.

steps to reproduce the issues

I installed a new Anaconda env and setup seabreeze via pip.

import seabreeze
seabreeze.use('cseabreeze')
#seabreeze.use('pyseabreeze')
print(seabreeze.__version__)
from seabreeze.spectrometers import list_devices, Spectrometer

devices = list_devices()

print ("Devices",devices)

spec = Spectrometer.from_first_available()

Output looks good but trigger mode 4 fails:

2.4.0
Devices [<SeaBreezeDevice USB2000PLUS:FLMS16723>]

And...

spec.trigger_mode(4)

fails...

--> 313     self._dev.f.spectrometer.set_trigger_mode(mode)

File src\seabreeze\cseabreeze\c_seabreeze_wrapper.pyx:682, in seabreeze.cseabreeze._wrapper.SeaBreezeSpectrometerFeature.set_trigger_mode()

SeaBreezeError: Error: Invalid trigger mode

If I switch to pyseabreeze, I get the following results in the following error.

2.4.0

    111 else:
--> 112     raise cls._backend.SeaBreezeError("No unopened device found.")

SeaBreezeError: No unopened device found.

Again, I can continue to run using my 1.3.0 install though I am not sure what I functionally will be missing if anything as I think most changes are related to other items.

[ap--]

It's very strange that pyseabreeze doesn't recognize the spectrometer with 2.4.0 but does with 1.3.0...

Could you post the commands used to create the 1.3.0 environment and the commands used to create the 2.4.0 environment?

Sure. It has been a while since trying that. I'll check and reply soon. BTW, I am using Anaconda for building python environments. Thanks
