Cannot snap an image from the ProEM CCD

[qianwu2]

Hi,
I am on Win11 using Python 3.10 (I tried other later version of Python e.g. 3.12 and would not work for me). Finally, I can see the camera, and am able to set and get attributes from the camera. However, when I tried to get an image, I got this error.

cam1.setup_acquisition()
Traceback (most recent call last):

Here is my code that I run before I got the point.

import pylablib as pll
import numpy as np
#C:\Program Files\Princeton Instruments\PICam\Runtime
pll.par["devices/dlls/picam"] = "C:\Program File\Princeton Instruments\PICam\Runtime"
#pll.par["devices/dlls/picam"] = "C:\Program Files\Princeton Instruments\PICam\Libraries"
#pll.par["devices/dlls/picam"] = "C:\Program Files\Common Files\Princeton Instruments\Picam\Runtime\Trace"
#C:\Program Files\Princeton Instruments\PICam\Libraries"
from pylablib.devices import PrincetonInstruments
#cam1= PrincetonInstruments.PicamCamera()

#PrincetonInstruments.list_cameras()
cam1= PrincetonInstruments.PicamCamera('2903120003')
#test = PrincetonInstruments.list_cameras()
#serialnumber = test[0][1]
#cam1 = PrincetonInstruments.PicamCamera(serialnumber)
cam1.get_attribute_value("Pixel Format")
cam1.set_attribute_value("Exposure Time", 10) # set the exposure time to 10 ms
cam1.cav["Exposure Time"] # get the exposure; could also use cam.get_attribute_value("Exposure Time")
10.0
cam1.get_attribute_value("ADC Speed") # df 2 for 2mhz
cam1.get_attribute_value("ADC Analog Gain") # df High
cam1.get_attribute_value("ROIs") #
cam1.get_attribute_value("Shutter Timing Mode") # df Normal
cam1.get_attribute_value("Sensor Temperature Set Point") # df -70
cam1.get_attribute_value("Sensor Temperature Reading")
cam1.set_roi(0,1024,0,1024,4,4) # set binning 4x4 to 256x256 image size
cam1.set_attribute_value("ADC Speed", 0.1) # set speed to 100 Khz
cam1.set_attribute_value("Sensor Temperature Set Point", -45.)
cam1.set_attribute_value('ADC EM Gain',47)
cam1.get_all_attributes()

It turns out that I had wrong camera setting. I used snap routine with a long timeout (200) and am able to read the camera.
