Testing with pyscope¶

In python command

form pyscope import tia
g = tia.TIA()
g.setExposureTime(200)
g.getImage()

You should get a bunch of numbers in a numpy array.

Trouble shooting¶

Some version of TIA may give an error of that at the end of it says

_ctypes.COMError: (-2147352567, 'Exception occurred.', (u"Camera 'tia' does not exist.''.u'ESVision', None, 0L, 0))

This happens because TIA scripting (ESVision) knows the camera by a different name.

The correct name may be in TUI/CCDCamera panel. Or you can find out from these python commands when the camera in question is active (You can make it active by acquire an image in TIA).

from pyscope import tia
t = tia.get_tiaccd()
c = t.ccd.Camera

You should get the camera name as the output.

With the name, edit pyscope/tia.py and change in the class TIA,
from

    camera_name='tia'

to

    camera_name='THE NAME YOU FOUND'
