Following the info found here: http://sparktronics.blogspot.it/2008/05/synaptics-t1004-based-touchpad-to-ps2.html 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?


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?
