h1. TIA-controlled camera (FEI Eagle)
h2. Extra Package and Installation
|_.program/package|_.notes|
|Tia.dll |(Should come with the microscope)|
{{include(comtypes installer)}}
h3. Run updatecom.py
* From a command line window:
<pre>cd C:\python27\Lib\site-packages\pyscope
C:\python27\python.exe updatecom.py</pre>
* The output sould contain one of these output
<pre>

Found ES Vision 3.1 Type Library done.
</pre>
h2. instruments.cfg
Eagle:
<pre>
[camera]
class: tia.TIA
zplane: 50
height: 4096
width: 4096
</pre>
h2. Setup
* Set camera configuration to give the [[Leginon Image Orientation|standard Leginon orientation]].
h2. Programs to open before Leginon Client: TIA.
h2. Testing with pyscope
h2. Trouble shooting
In python command
<pre>
form pyscope import tia
g = tia.TIA()
g.setExposureTime(200)
g.getImage()
</pre>
You should get a bunch of numbers in a numpy array.
h2. Trouble shooting Programs to open before Leginon Client: TIA.
Some version of TIA may give an error of that at the end of it says
<pre>
_ctypes.COMError: (-2147352567, 'Exception occurred.', (u"Camera 'tia' does not exist.''.u'ESVision', None, 0L, 0))
</pre>
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).
<pre>
from pyscope import tia
t = tia.get_tiaccd()
c = t.ccd.Camera
</pre>
You should get the camera name as the output.
With the name, edit pyscope/tia.py and change in the class TIA,
from
<pre>
camera_name='tia'
</pre>
to
<pre>
camera_name='THE NAME YOU FOUND'
</pre>
