PS2 controller to PS / 2 mouse: PIC? Arduino? Custom Logic?
The problem is the communication with the PC. I'm studying A-level Electronics, so I understand the protocol, but a logic circuit would be massive unless it was on a custom chip.
I've found a microchip that can handle the PS2 communication, but its inputs are for light gates, like you might find in an old ball mouse.
The other thing I considered was a PIC or Arduino (which I've been wanting an excuse to play around with for ages).
Anyone got any ideas?
