40 | |||
41 | In python command |
||
42 | <pre> |
||
43 | form pyscope import tia |
||
44 | g = tia.TIA() |
||
45 | g.setExposureTime(200) |
||
46 | g.getImage() |
||

51 | 4 | Anchi Cheng | h2. Trouble shooting |
52 | |||
53 | Some version of TIA may give an error of that at the end of it says |
||
54 | |||
55 | <pre> |
||
56 | _ctypes.COMError: (-2147352567, 'Exception occurred.', (u"Camera 'tia' does not exist.''.u'ESVision', None, 0L, 0)) |
||
57 | </pre> |
||
58 | This happens because TIA scripting (ESVision) knows the camera by a different name. |
||
59 | |||
60 | 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). |
||
61 | <pre> |
||
62 | from pyscope import tia |
||
63 | t = tia.get_tiaccd() |
||
64 | c = t.ccd.Camera |
||
65 | </pre> |
||
66 | You should get the camera name as the output. |
||
67 | |||
68 | With the name, edit pyscope/tia.py and change in the class TIA, |
||
69 | from |
||
70 | <pre> |
||
71 | camera_name='tia' |
||
72 | </pre> |
||
73 | to |
||
74 | <pre> |
||
75 | camera_name='THE NAME YOU FOUND' |
||
76 | </pre> |
