I am looking to design a USB mouse using Flowcode. The USB side is as everyone knows a doddle but has anyone designed anything using the old opto wheel thing for direction please?

I put "Mouse" in the search bar but too many posts came up...

Hi James,

The quadrature encoder component might be useful to you. It's basically a way of using two sensors on a single encoder to detect speed and direction. It think this is primarily how mice do it.
