There are two things w.r.t touchscreen: - The touch operation itself - is the driver loaded? are you getting touch interrupts? - Calibration - mapping the usable area so that the touch interacts with the correct display element (icon etc) Some information is at the AOSP page: http://source.android.com/devices/tech/input/touch-devices.html FYI, In the TI DevKit kernel (3.2) the touch calibration data is part of the platform data for the touch driver. See my post in android-porting for more information about this: https://groups.google.com/d/msg/android-porting/CpP4xCk0U_g/DaCoAmqj6FwJ -Vishveshwar > > I did manage to get GApps (google play etc.) + SuperSU working on the > TI_Android_JB image, and i'd gladly provide details if requested. > > Thanks > paccer > -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
