This version

DS4Lib 1.0 adds touchpad tracking. You can get the status of the new pressable buttons (TPAD_CLICK, TPAD_TOUCH) declared in buttons with the usual button_pressed() function. You can also retrieve the coordinates of your finger on the touchpad with the new 'ds4_get_tpad_coord(DS4_CONTROLLER * ds4)' function.

Touchpad-coordinates: (adjust at your will. Take into account touchpad, dimensions (52mmx23mm (external approximately))[source: http://www.psdevwiki.com/ps4/DualShock_4];
