Using the UPDD utilities

Currently with Android we supply only the driver and the Command Line Utility.

The UPDD command line utility is included as a means to adjust the software settings and list driver and controller configuration information and is invoked as follows:

cd /system/vendor/updd
./upddenv ./upddutils [parameters]


The driver reads calibration data from the device's HID Report Descriptor so in theory should be calibrated after the driver is running.

However, should calibration be required the command line utility can be used to perform a simple corner calibration by running the command ./upddenv ./upddutils calibrate

You will be prompted to touch the corners of the screen, touch as close as practical to the corner.
