/** \file led_cam_ctrl.h
* \brief Digital Camera Control
*
* Provides the control of the shutter and the zoom of a digital camera
* through standard binary IOs of the board.
*
* Configuration:
* Since the API of led.h is used, connected pins must be defined as led
* numbers (usually in the airframe file):
*
*
*
*
* Related bank and pin must also be defined:
*
*
* The required initialization (dc_init()) and periodic (4Hz) process
