Hi Franz

Many thanks indeed for your kind update and it will now make my life much easier 😀

Unfortunately I don't contribute whatsoever to the coding of the Teensy USB Development Board as this is kindly provided by my friend Berger, so I am not in a position to comment on the communications of the board.

The interesting comment by Berger about communicating with the Certabo electronic chess boards is that I own one and to be able to use it with your software would be the ultimate chess board for me personally 👍

Many thanks again for the update

Regards from England
Bryan
