Function 'GetPreAmpGain' raised error 20066(DRV_P1INVALID)

[whooie]

I'm trying to set up control of an Andor iXon Ultra 888 using this library and can't connect due to a DRV_P1INVALID error raised in the execution of this line:

https://github.com/AlexShkarin/pyLabLib/blob/f935595f20057330a58934afecc4a9d467bd2969/pylablib/devices/Andor/atmcd32d_lib.py#L660

which was called involved in the execution of

https://github.com/AlexShkarin/pyLabLib/blob/f935595f20057330a58934afecc4a9d467bd2969/pylablib/devices/Andor/AndorSDK2.py#L174

following the original connection attempt,

from pylablib.devices import Andor
cam = Andor.AndorSDK2Camera()

Seems like it shouldn't matter, but just to be thorough this is using a pylablib-lightweight[devio,gui-pyqt5] installation on Windows 10.

Could you check your Andor SDK2 version?

Accroding to its changelog, version 2.94.30001.0 fixed bug stating Fix for SDK defaulting to using an unavailable PAG for iXon 888. That could be the reason you're experiencing this issue.

If updating SDK2 version does not help, you can try moving preamp_gain=self.GetPreAmpGain(pa) (line 660 in atmcd32d_lib.py) inside the try block immediately following it, i.e., move it one line down and add an extra indent. This should get rid of this particular error, although there might be similar error further down the line (e.g., when trying to get or set the preamp gain or the amplifier mode). If you do try this, could you also report the result of executing cam.get_all_amp_modes()?

I'm using SDK version 2.104.33000.0.

I tried making that change in atmcd32d_lib.py and got DRV_NOT_SUPPORTED from SetNumberPrescans. Here's the traceback:

Also, here is the output from get_all_amp_modes (I printed them from the AndorSDK2Lib call in atmcd32d_lib.py since the camera didn't get fully set up):

OK, it looks like there are still some capabilities which are not always supported, but which the class does not check. Could you replace the line 704 in AndorSDK2.py (it's the lib.SetNumberPrescans(num_prescan) line which raises the error) with

        if self._check_option("set",AC_SETFUNC.AC_SETFUNCTION_PRESCANS):
            lib.SetNumberPrescans(num_prescan)
        else:
            num_prescan=0

I apologize for such awkward step-by-step debugging, but the documentation is not always 100% clear on which errors can arise in which situation, and which functions may or may not be available.

[whooie]

That seems to work -- at least no exceptions are thrown now when I connect to the camera. I'm still in the process of setting everything up so I don't have any tests I can run to make sure it fully works, but I'll let you know if I encounter anything else. Thanks!
