Hi,

i wanted to use an optical mouse(usb mouse)for my project,which does not include a computer.can anyone please tell me how the data is sent to the computer by the mouse on moving it?

thank you

 

How does it track or how does USB work?

 

Nearly all optical mouse uses optical sensor IC that communicates with the outside world using SPI protocol. The movement is reported as data in both X and Y direction.

You can interface with it using SPI to your MCU of your project.
