This is something ive been wanting to try for a while.
To use an optical laser mouse (no balls) and a picaxe for accurate position sensing.
Most mice these days are usb i.e. they contain a chip that converts rs232 to Usb. which can be ripped out I guess but I still see mice with the PS/2 connection (serial)
I have seen various attempts to use both usb mice and PS/2 mice for position sensing. One thing that interested me was the PAK XI chip http://www.awce.com/pak11.htm which you connect to the mouse and a picaxe or basic stamp available for around 24 USD
In "experiments in mechatronics using the picaxe controllers" by David Lincoln it features a circuit (attached) where you can interface with an ASCII Keyboard using a PS/2 connection with an 18A. The circuit also includes an LCD interface which does not interest me. But my question is this, If a keyboard can be interfaced with a picaxe why cant a mouse?
Perhaps using the shiftin shiftout commands
I am looking to use it on a small robot to work out its position on 1m square floor.
All of the optical laser mice using USB that are used for this purpose have had their rs232 to USB chip removed. What I have found is that in every example the mouse has an Avago ADNS - 2610 optical mouse sensor. These are quite hard to come by in New Zealand
Has anyone ever attempted this?
