USB2000: spec.intensities causes infinite loop (due to old FW) about python-seabreeze HOT 9 OPEN

Hello Andreas,

I think you can go ahead and close this issue.

With a lot of trouble shooting, blood, sweat, and tears, i finally found the fix!

It turns out, my USB2000 Ocean Optic Spectrometer never had the firmware updated.

The firmware is required in order to run it on Mac, Windows 8, and Windows 10.

The only way to get the firmware is to email Ocean Optics Technical Support and they will send you the update file with instructions on how to install the firmware on to your device.

I successfully installed the firmware and now my spectrometer runs perfect!

Thank you for all your help!

Update, after I left the program running for a long time, it finally gave me this error

Hey aoabdelatif,

can you try the same outside of spyder in a python interpreter and report back?

All the best,

Hey Andreas,

Thank you for the speedy response.

So would you recommend using IDLE?

Just open your anaconda python interpreter from the command line (Terminal).
(open your terminal app and type python. Note: it should say something like python 3.6.1 anaconda..., if not, you need to export your Anaconda path)

It's possible that spyder or idle do some extra things, that might interfere.
If the problem is still there in a plain python interpreter, we need to investigate further.

Andreas,

Here is a screen shot of what my terminal looked like after i ran the same functions as i did in spyder.

Once used the spec.intensities() function, the same thing happened as before, the terminal line got hung up once again. (Ive been waiting for awhile and its still hung up)

MacOSX Sierra 10.12.1
Python 3.6.1
Anaconda 4.4.0
USB2000

I really appreciate your help with all this,

-Adam

ps.
I hope this doesn't turn you off from helping me but i also downloaded the OceanView Free Trial and for some reason OceanView gets hung up when i try to connect to the USB2000, Ocean View does recognize the USB2000.

Hmm, this is very strange.
It should return immediately...

can you run this in your terminal:

pip install pyusb

then run python and run:

import seabreeze
seabreeze.use('pyseabreeze')
import seabreeze.spectrometers as sb
devices = sb.list_device()
spec = sb.Spectrometer(devices[0])
spec.intensities()

HI Adam,
Thanks for the report. I'll leave the issue open, until I add this info to the README at some point.
Glad that it works now :)
