Hi,
I'm planning to use epics, but I"m stuck right at the beginning.
I work on scientific linux 6 so first I start python:
ipython
Python 2.7.5 (default, Jun 5 2014, 14:38:05)
Then I try simple epics commands:
In [1]: import epics
In [2]: p = epics.PV('LargeWaveform')
In [3]: p.connect
Out[3]: <bound method PV.connect of <PV 'LargeWaveform': not connected>>
But I am unable to connect any of my PVs. Am I doing something wrong?
'connect' is a method of a PV. To run this method, add parens:
p.connect()
The connection should happen automatically and soon, so that you don't need to explicitly run the connect method, and can just access the data:
p.get()
You can also checked the value of `p.connected`, which will be True once (and if) the PV is connected.
