JEOL setup¶

instruments.cfg¶

[TEM]
class: jeol1230.jeol1230

Testing pyscope instrument script functions¶

On the instrument host of the instrument, a TEM host that uses Tecnai class, for example, you can launch python command line window and try to create an instance of the instrument and then call a function such as getMagnifications in that like this:

import pyscope.registry
s = pyscope.registry.getClass('jeol1230')()
s.getMagnifications()

Potential problems¶

import serial¶

>>> import pyscope.registry

  File "c:\Python25\Lib\site-packages\pyscope\jeol1230lib.py", line 8, in <module>

you need to install "Python Serial Port Extensions" http://pypi.python.org/pypi/pyserial
