Detailed Description

Digital video/photo recorder HackHD control.

Provides the control of the HackHD power, start and stop of recording. If you are using firmware >= 1.1.15, it is also possible to take pictures according to the parameter in the config.txt file (on HackHD SD card). It is not possible to have both video and photo at the same time. This driver starts the HackHD in standby mode and trigger the start/stop of recording or take a picture. Minimum time between two pictures is 2 seconds.

It is mandatory to configure the control GPIO:

*   <configure name="HACKHD_GPIO" value="GPIOC,GPIO5"/>
*
