Thanks Klaus ... I'll try to make a post in the forum (in the B4i wishlist forum)Not in a near future.
I will look to make a Class, no time schedule, I don't have the knowledge to write libraries.
Just to be clear, the library was written by Andrew Graham (agraham).
I made a small change in the library, and as Andrew is now less active in the forum Erel changed the ownership of the first post from agraham to mine (with Andrews agreement) to let me update the first post.
I wrote the demo program.
