You can use either the resistive sensor ( left + middle + right with stylus-class pressure) or the capacitive sensor (middle portion with fingertip), but not both at the same time. If the pad detects resistive (stylus) activity, it switches to a different mode and sends you data packets reflecting stylus activity across the surface. When the resistive activity stops, it switches back to capacitive sensing after a short delay. We originally hoped to be able to send information from both sensors "simultaneously", but that proved to be *really* flaky. In any case, the left and right panels can't sense fingertip pressure - you would have to use a fingernail, and that would override the signal from capacitive sensor. _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
