BASIC Stamp II & PS/2 mouse - more

Hi all,
Thinking some more on this project, there is no reason why I couldn't use a
serial mouse into the Stamp and generate the PS/2 codes to the PC.

Jean-Michel.

How is your project progessing ? I'm also very interrested, because i
would like to emulate a ps/2 mouse with a basic stamp, I already
destroied about a dozen of ps/2 mouses trying to....

I've seen something about mouse and Stamp in the LOSA (List Of Stamp
Application).
I don't know the link, but it is one on Parallax'site.
Hope this helps...
Phil.

It's progressing slowly.
The first thing to realise is that a BS2 or BasicX-24 just isn't fast
enough to handle the data stream from a PS/2 device. What I have opted for
at this stage is to use dedicated protocol converters which are available
from USAR (http://www.usar.com/). Once I have my prototype running I'm
then going to write the PS/2 routines in assembler using a 16F84.
At the moment I'm still working on the 240x64 graphic display.

Jean-Michel.
1) Reading a PS/2 device. There is no doubt the BS2 is not fast enough.
That's why we make the PAK-VI which can read a PS/2 keyboard or mouse,
buffer it, and present it to the BS2 or any micro for that matter.
2) Writing to a PS/2 port. Here I'm not so sure. The PS/2 device generates
the clock and it is not clear to me that the PC won't let you go as slow as
you like (within reason). Therefore, I think the Stamp could fake a PS/2
keyboard or mouse, but I'm not sure. Hmm.... maybe a project of the month in
there.

Yes I had a look at your chip, unfortunately it only does 1 half of the job
that I need.

From what I can see, you can send PS/2 from a BS2/BX24 to the PC, however
as I said in my last post, reading from a device such as the mouse,
keyboard or the PC just ain't gunna happen. :-)
