PixArt Imaging PAT6125 is a miniature low power optical navigation chip using LASER light source enabling digital surface tracking. This device driver use IIO API to provide ponctual and/or buffered data. The data is the delta value between two position traveled, depend on CPI (Counts Per Inch) resolution setting chosen. The retrived data is composed by two values, delta on the X and Y axis. Unfortunately, the device doesn't support "on-the-fly" configuration.
