First of all, thank you for taking the time to answer me. Yes, it is a valid library, and I have already worked with this library and coded a lot. I have encountered this problem since I installed Arduino 2.3.2. I installed it again, but it is still not fixed. I also used the previous versions and it still has a problem. I don't know what to do. Believe me, I have reached the point where I want to cover and burn everything
