Arduino Leonardo and touchpad

Projects General Guidance
1

Following the info found here: Sparktronics: Synaptics T1004 based touchpad to PS2 port I was able to interface a Laptop touchpad to the PC, through Leonardo HID device.

Everything works fine: X, Y, Left and Right click and it acts as a mouse 100%.

What I can't manage is the scroll gesture. Synaptics T1004 ic has some pins to receive horizontal and vertical scroll (active LOW - I suppose for external controls), but I can't get how to handle. Any idea?

hi
I can't help with your problem, but am writing to ask for your help, I would like to do what you have done, how do you get the trackpad absolute coordinates to the computer?
