Python CFFI wrapper for the Opal Kelly FrontPanel FPGA interface.

To use this module, you need to have the Opal Kelly FrontPanel C interface installed correctly so your C compiler can find the okFrontPanel shared library and the okFrontPanelDLL.h header.

You have to sign up at OpalKelly to be able to download okFrontPanel.

Get Opal Kelly FrontPanel, at least v4.5.6 and install it.

Get the Visual C compiler and install it.

pyOKFrontPanel should find your FrontPanel installation from the OKFP_SDK environment variable.

FrontPanel for Linux is typically installed in /usr/local/, so make sure that your C compiler can find header files in /usr/local/include and that your linker can find dynamic libraries in /usr/local/lib.

Also make sure that you have installed the header files for the Python version that you are trying to use the FrontPanel with (in Debian-based distributions, this package is called python#.#-dev).

If the prerequisites are fulfilled for either Windows or Linux based systems, then you can install the OpalKelly Python Wrapper via

pip install pyOKFrontPanel

which will trigger the compilation of OpalKelly Wrapper together with the header file (okFrontPanelDLL.h) of the front panel by using the mentioned C compiler above.

Sometimes clang is unable to find the header file (okFrontPanelDLL.h), in that case set the following environment variables:

export LDFLAGS=-L<path to lib>
export CPPFLAGS=-I<path to include>

For example:

export LDFLAGS=-L/usr/local/lib
export CPPFLAGS=-I/usr/local/include

Then run pip again.
