This project provides a Python wrappers for the Finger Lakes Instrumentation SDK libfli-1.104 on Linux. It exposes all the public functions and macros with the following exceptions:

FLICreateList
FLIDeleteList
FLIListFirst
FLIListNext
FLISetDAC
FLIDebug

The wrapper signatures are not precisely the same as the Finger Lakes functions. For instance, functions that fill user supplied buffers return numpy arrays instead, C strings are returned as Python strings, and some arguments are passed as strings instead of C macro values.

All the wrappers have document strings that follow the Numpy documentation standard. Some of the functions in the SDK were undocumented and FLIGrabFrame was a stub. In the first case the lack of documentation is noted where applicable, and for the second FLIGrabFrame was implemented in a way that seemed appropriate to its name.

Some of the functions require knowledge of the ADC precision and may segfault if it is incorrectly specified. Finger Lakes doesn't currently provide a way to determine the operative precision, so it is up to the user to be careful and track the precision in use.

Both Python and Numpy are needed for installation. The supported versions are Python 2.6-2.7 and Numpy >= 1.5. These versions are probably conservative and it is likely that earlier versions will work. Python 3 is not currently supported, but as far as I know the only things that may create difficulties are strings. One case that will definitely cause trouble is noted in the pyfli.pyd source.

Tested on Linux 3.6.10-2.fc17.x86_64 Fedora 17. FLI SDK 1.104 and FLI Linux USB driver 1.3 from http://www.flicamera.com/software/index.html are provided.

Another option for those interested in Python FLI support is Craig Versek's ctypes based wrappers https://github.com/cversek/python-FLI.
