Hi ludo
I'm trying to read out data from a Cirque 9920 touchpad.
I just saw on one of your photos, that you were using a similar type of touchpad...
What I am trying to do is to catch data from the finger position BEFORE I start moving it.
The regular PS/2 protocol gives you only delta values of the position. When I configure the pad to send automatically (stream mode) it only sends data, when a finger movement occurs.
In the (small) specification PDF for the touchpad, it sais something about an extended packet mode where I can get even the Z value (finger press). You have to change a hardware configurable option for that. On the back of the pad you find some connections you have to bridge to enable this options.
...I'm really hoping you (or someone else) know(s) what I am talking about and can give me some advice how to read out this data.
Thanks!
Marcel
