Hi Dean,
It looks like you are using the wrong backend. Please try
import seabreeze
seabreeze.use("pyseabreeze")
from seabreeze.spectrometers import Spectrometer
spec = Spectrometer.from_first_available()
spec.trigger_mode(4)
Cheers, Andreas
Edited:
Hi Andreas, As far as I know, I am using pyseabreeze not cseabreeze. I tried both earlier.
Here is that part of my code:
# explicitly request pyseabreeze
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()
#spec
try:
spec = Spectrometer.from_serial_number("FLMS16723")
except:
print("Already open. Moving on now.")
I will try your suggested minimal code above in a few minutes. Thanks, Dean
Hi Andreas, I am not quite sure why but it is working with 1.3.0 now. I suspect it was an issue with my code I somehow fixed or it was the driver. I am not sure why but the Gamry Framework code still has a driver for ocean insight and that seems to always take over from the Ocean Optics driver. Also, I still have not got 2.4.0 working but I still have a few things to try. Anaconda doesn't seem to be releasing the spectrometer after using 1.3.0 despite restarting the kernel and stopping the 1.3.0 environment. I'll work on that and if I can't get the current version working I'll ask about that. I wonder if I will need to disconnect the usb cable and reconnect to release it. Anyway, I'll close this issue. Thanks! Dean

steps to reproduce
We addressed (fixed?) the edge trigger issue back with closed issue #97 and again in #126. That seemed to function on and off in 1.3.0 as far as I can tell. I have new students now back on this project and now now setting trigger mode to '4' fails both in 1.3.0 and in the latest 2.4.0.
I followed the normal steps to get Flame-S talking to py-seabreeze and then change trigger mode via:
and it fails / errors but modes 0, 1, 2, and 3 all are able to be set.
After the changes as referenced in #97 I used to be able set to trigger_mode to '4' and it was triggered properly from my Camry potentiostat as far as I could tell. I checked devices.py and the changes made back in #97 and #126 were still in play. I did switch back from the Gamry driver to the Ocean Optics Driver as the Gamry driver seemed to get chosen by the OS. I don't think I have changed anything I am aware of but mode 4 fails with the following error:
I am at a loss what else to try. Thanks, Dean
