Licenses of libraries

Hello,

is possible to use library ezButton ezButton - Arduino Reference in project of my customer? He has a motor driver based on Atmega 328p with Arduino bootloader and for his update I would need ezButton library.

Is it possible to use for commercial use without code publish?

Thank you

Did you read the licence conditions in the source code of the library ?

Otherwise there are no clear restrictions on commercial re-sale - HOWEVER, since code is copyrighted (in the EU this happens automatically; in the US in principle as well, but registering copyright tends to help the author to assert their rights in any legal proceedings), it might be wise to check with the authors if commercial repackaging would also still fall under their conditions. If so, you should be safe provided you adhere to the limitations they laid down (which continue after the bit I quoted above).

Solved. I wrote to the author of the library, he gave me permission and asked for a contribution. I'll contribute to him and that's the end of it.
