i cant turn the lamp on

[chesse20]

spectrometer and system information

USB 4000
windows 10

current problem

i don't understand how to turn on the lamp, i tried following the api and it gets confusing to read. Can you add an example to the api page, i can't get data if the lamp is not on.

steps to reproduce

1. run code example
2. get error

minimal code example and error (very helpful if available)

my code and comments

##in python console
## pip install seabreeze
## pip install matplotlib
from seabreeze.spectrometers import Spectrometer
import matplotlib.pyplot as plt
spec = Spectrometer.from_first_available()

###
#NOTE
#this code does not work unless you turn the lamp on!
#turn the lamp code
#
spec.f.SeaBreezeStrobeLampFeature.enable_lamp(1)
###
spec.integration_time_micros(20000)
print(spec.wavelengths())
plt.plot(spec.wavelengths(),spec.intensities())
plt.show()

spec.f.SeaBreezeStrobeLampFeature.enable_lamp(1)

AttributeError: 'FeatureAccessHandler' object has no attribute 'SeaBreezeStrobeLampFeature'

Hi @chesse20,

If your IDE supports code completion and you have installed seabreeze>=2.0.2, it should help with this, by suggesting the available attributes on the spec.f attribute. Please try the following:

from seabreeze.spectrometers import Spectrometer
import matplotlib.pyplot as plt
spec = Spectrometer.from_first_available()

spec.f.strobe_lamp.enable_lamp(True)
spec.integration_time_micros(20000)
plt.plot(spec.wavelengths(), spec.intensities())
plt.show()

And let me know if it works.

Cheers,
