PythonForPicam

PythonForPicam is a Python ctypes interface to the Princeton Instruments PICAM Library Copyright (C) 2013 Joe Lowney. The copyright holder can be reached at [email protected]

pypicam is a module that provides basic access to the first camera loaded by the system. This module was added as part of our development of a PyZMQ client/server model for passing image data (see https://github.com/DawesLab/Camserver) Andrew M.C. Dawes - [email protected]

A Python Interface for PICAM Library

The interface can nominally be run by building Main.py

The interface uses the built in Python ctypes module. The interface reads in a library, Picam.dll, provided by Princeton Instruments at ftp://ftp.princetoninstruments.com/Public/Software/Official/PICam/

Main.py is the main application. When compiled, Main.py reads in external types defined in PiTypes.py and PiTypesMore.py as well as functions from PiFunctions.py. PiParameterLookup.py is used to read in camera parameter values. This is mainly a workaround to address the fact that Python ctypes does not have a built in enum class.

2013 June 26 -- Initial Release

Main.py PiTypes.py PiTypesMore.py PiFunctions.py PiParameterLookup.py

2013 December 8 -- Modifications for use in Linux (DawesLab)

  • Import libpicam.so library instead of DLLs
  • pypicam.py is written as a basic module to provide simple access to the first camera loaded by the system.

2016 January 13 -- Modifications to run under Python 3

Simply replaced all print ... statements with print(...) statements. To use this under python 2, simply checkout commit a970928 instead of the latest.

TODO

Handle some of the enum types in the Picam properties. Settings like TriggerResponse need to be set as integers now since there is no lookup table for these options. Parse picam.h to generate the necessary info.
