What does -1, 1, 2 mean?

[alchle]

Kristopher,

This looks very promising for me to detect mouse speed. I am working on a project for my wife who wants to have constant stitch length when sewing quilts. The faster she moves the quilt the longer the distance between stitches, and the slower she moves it the closer they are together. She wants equal distance no matter has fast she is moving the quilt. I figured out how to control the needle's stitch speed on the sewing machine with a digital potentiometer but need to transfer the speed at which she is moving the quilt to the arduino in order to control the needle speed (potentiometer).

What does the -1, 1, 2 mean in the output?
I've tried to calculate speed by sqrt(abs(x)_abs(x) + abs(y)_abs(y))
with x=data[1]
with y=data[2]

But the velocities are not matching how fast I am moving the mouse.

Any help would be appreciated. Thanks

-Allen

Allen,

I haven't touched that lib since 2009 :/ but here are some resources that
maybe helpful

Good overview of how the ps2 mouse communication works http://www.computer-
engineering.org/ps2mouse/

My lib is used in this book for a couple projects
http://www.practicalarduino.com/projects/ps2-keyboard-or-mouse

Cheers,
Kris

I'd check out the PRs and Forks, I think there are some more recent updates
for newer versions of the Arduino SDK
