What is the license this code is released under?

[pastly]

I have been picking out the useful functions in this library, fixing them, and modifying them for my project. I would like to know if I have permission to share them.

There currently does not seem to be a license. Could you please add a license of some sort?

If you want suggestions, I would highly suggest an public domain license such as CC0 or the Unlicense. The MIT license is popular.

I think that's important too. Even if this seems like a PoC demo (and it's in the best interest of Waveshare to let us reuse their code in order to use their products), an explicit license clearly stating that we can use this code would be very welcome.
