Hi Again All,
I have been looking for a tutorial or howto or alike to show me how to use an optical mouse as a linear position sensor without having it plugged into a PC's USB port. Basically, I'm looking for some sort of information so I don't have to do all the fine detail learning myself.
I have skimmed over http://www.usb.org/developers/devclass_docs/HID1_11.pdf
but this is far more than I wish to know to be able to use the optical sensor as a linear position sensor.
Without having to learn all the internal workings of the USB protocol & then all the mouse workings is there an easy way of acquiring just the X/Y motion information from an optical mouse, say by simply scanning for every 5th byte or bit (just grasping at thin air here!) or something?? I would like not to have the mouse plugged into a USB port but wired into a simple data acquisition PCB of my own design.
Hopefully One of you Linux / Electronics Geniuses's out there has done all the hard work for me & can point me in the right direction!
