License? about adafruit_bme280_library HOT 5 CLOSED

Just noticed that the source files mention the BSD license.

I'll leave this issue open for now, since most people probably look for the license in either a file called LICENSE or COPYING.

@kankaristo thanks for the feedback; If you wanted to submit a PR I'd be happy to review it

I'd be happy to make a PR, but there are actually a few different versions of the BSD license, and the license mention in the source files don't specify which one:

• 2 clause BSD
• 3 clause BSD ("New BSD")
• 4 clause BSD ("Original BSD")

The 4 clause BSD license is considered "problematic", because it includes a clause that all marketing material must include this sentence verbatim:

This product includes software developed by the University of California, Berkeley and its contributors.

So, that leaves the 2 clause and the 3 clause licenses. The only difference between those licenses is this clause:

Neither the name of nor the names of its contributors may be used to endorse or promote products derived from this software without specific prior written permission.

The 3 clause license is probably more common, and if you ask for permission to "promote" the fact that your software uses Adafruit libraries, the 2 and 3 clause licenses are identical. And the line between "promotion/endorsement" and simple "acknowledgement" is up for debate.

I'll make a PR for the 3 clause BSD license + mention of the LICENSE file in the source files.
