Thanks for the information. I created a library.properties file as well as a new release. I believe it is now in 1.5 format.
@BlueDot-Arduino There is no license information about your library, please add one :) .
Ops! Thanks again for the information.
I made a few changes and I guess now the library should be complete! :)
Done thank you!
