Re: [avr-gcc-list] PS2 mouse interface code

[Keith Gudger]

I have code for a PS2 mouse that works on a 43USB325.  I can send it to
you off list if you would like it.  Be forwarned that it is part of a USB
keyboard (which acts as a PS2 mouse master), so there is keyboard and USB
junk sprinkled in the code.  Let me know if you want it.
