Re: RCX and NXT communication
amoose,
The rotation sensor used in the RCX version is simply a wheel with light and dark places and a photo diode/LED combination. As I remember it gives 16 output transitions per rotation. The NXT version has better resolution and that is why it can be used for angular detection. Remember that the RCX has only two wires per port. I found this in a quick search that might be something interesting for you.
