I'm interested in learning more about trackpads, with a view to add one to an electronics project. Rather than buying a trackpad and hooking it up to an arduino to see if it meets requirements, I figured I'd use the Mac trackpad I already have.
I really just want to see what the shape of the incoming data is, pipe it to a file, and process it later on (at least that's what I'll be doing in my electronics project).
Is it possible to do this with a mac trackpad? Just log the incoming data (time-series coordinates I imagine), throw it in a file.
Thanks!

Google tells me you can use WireShark to capture packets (https://developer.apple.com/forums/thread/95380) after disabling system integrity protection (https://developer.apple.com/forums/thread/124875)
I wouldn’t know whether that works today. Also, it wouldn’t be “time-series coordinates”, but that information would be in the data captured.
