HELP!! Mouse encoder for robot.

azmax100

Hi all,

I am trying to use mouse encoder for mapping but i don't know how.
Here is my Track Bot: http://forums.parallax.com/forums/default.aspx?f=21&m=211720

Can anybody guide me? I need to know how to implement this encoder to my robot such as what hardware do i need.

Thanks in advance.

The stamp is to slow to interface directly with a PS2 keyboard/mouse.
AWC Electronics provides two custom uprocessors complete with ceramic resonators that provide an interface between a PS2 mouse and a TTL RS232 9600 host. Such as a Parallax Stamp.
Links, applications notes complete with PBasic code to interface to the Parallax BS2 products are attached.
Mouse X & Y registers, direction, overflow·and buttons can be interfaced.
Somewhere on u-tube there is a robot utilizing a track-ball mouse. Google/Yahoo it.

Hi Stephen,

Thanks for the feedback. I've take a look at the pak6 but i think it's too complicated for a newbie like me.

Anyway I after google for some time i found this encoder circuit by Ibrahim Kamal on his web site.

He's using LM 358 but know the problem is how am i going to connect this encoder to Basic Stamp what command to use in Pbasic. I just want somebody to guide me trough this process and i am going to code by myself.

Here i attached the circuit and the complete assemble parts photo.

AWC's products are pretty easy to use... if they are too complex, I sugest Parallax's BOE-Bot Digital Encoder Kit (http://www.parallax.com/Store/Microcontrollers/BASICStampModules/tabid/134/txtSearch/encoder/List/1/ProductID/80/Default.aspx?SortField=ProductName,ProductName). It will give you all the parts and clear documentation and code examples.

Just another link for a product that might work for you: http://www.multilabs.net/ezMOUSE.html

I have·never used it but it looks pretty easy to use. Hope this helps.
