I see, that sounds more and more like it actually communicates with the other CPU then.
Not for the chess engine calculations, but for button presses and such.
Yes, I think so. It is a little bit like with the final chesscard and the C64. Sound, peripherals, etc are controlled by the C64 and its CPU while the Chessprogram on the card is controlled by its own CPU
The only difference is that in this case the chessboard also has an own chessprogram, which is also available with the module plugged in by selecting one of the levels beginning with a, b or c. What I don't know is, if the board position is still available if I change the level in the middle of a game from e.g. f3 (module level) to e.g. b2 (standard level) or vise versa. But maybe someone who has a Leonardo or Galileo can test that.
