Hi all,
I have one question about the lib ps2!
Can I connect an optical mouse or this is designed only for wheel mouse?
have any difference?
sorry for the english. :-/
Att,
if its a ps2 mouse it should act the same way regardless of how it gathers its information
ps your English is fine 
The standard microsoft optical USB mice are ps2 compatible.
Mowcius
From the protocol (and PS2 lib)point of view, it is not important, what is inside a mouse (optics or ball). A basic mode works for both.
Thx everybody.
I've tried the lib ps2 on both, and it works very similar!
But the optical, it's responding a little bit fast than the ball model.
thx again.
att, denadai.
yea most optical mice have a resolution in the thousands, and ball mice are in the hundreds, so it will be faster
@denadai, denadai i've tried USB optical mouse to interface with arduino but i couldn't get it right. i use martijnthe tutorial on how to interface with optical mouse PS/2.... you said that you have already successful on getting the USB mouse correctly, could you give me some picture which one should i connect to the arduino? because i just can't solve which cable should i solder..
thank you very much..
you said that you have already successful on getting the USB mouse correctly,
Where was that said?
Whether a mouse is optical or ball-based has nothing to do with the interface to the PC. The first optical mice used PS/2 for communication.
The PS/2 Protocol and USB are entirely different. A tutorial on a PS/2-based mouse will not work with a USB-based mouse.
Thx everybody.

i thought that the lib ps2 he means was the library of ps/2 mouse that interfaced using arduino. so the arduino can read of its coordinates/speed.. CMIIW..
The PS/2 Protocol and USB are entirely different. A tutorial on a PS/2-based mouse will not work with a USB-based mouse.
yeah i know,.. at least i want to know to work on PS/2 mouse which i failed to work on.
for your info, i've already killed 4 mice and ended up with nothing :'(..
i've done 3 PS/2 mice and 1 USB mouse.. but all i did was using martijnthe tutorial on mouse interfacing. and now i found this thread that do some different approach.. so i need some hint to do it right..
thank you..
