Hier mal der Quellcode der Touch Test API. Vieleicht hilft das ja weiter :-)

/*
This example shows how to receive touch event and the x,y value from the board.
This example use vm_touch_register_event_callback() to register touch handler.
when touch the lcd on the board,the touch event and x,y value will be sent to application
through this handler.
Just run this application,and see the catcher log or monitor log or lcd.
