Nothing yet. I have a guy in England that's trying to use pbForth to
do I2C comms. As I see it, there are two possiblilities here. One
is a bit-bang interface on a sensor input port. Tricky to do with
pbForth because it allows the normal 1 msec interrupt to run which sets
the voltage low on the sensor pins every 3 msec.
Another option is your suggestion of a simple IR interface. pbForth
can easily change its baud rate to sample the mouse info.
A final option is a PIC that gives us X/Y info on two sensor inputs....
More thoughts?
Cheers, Ralph
