Elecrophoretic (e-paper) displays often use a .fw "waveform" file, generated by a tool, for driving the displays. This waveform file is a lookup table (LUT) of timings, voltages, and temperatures for driving a panel of specific electrical characteristics.

Since it seems this LUT is not created as a form of art (being auto-generated) and it is also a raw representation of driving properties, my gut tells me this isn't copyrightable because facts can't be copyrighted.

Are there any lawyers here who could weigh in? Can these waveform files be freely shared, and do they belong to the public domain?

Thanks.
