The following structures have been defined for IPC between the
sbcController and the camera control processes.

---------------------------------
To the camera
---------------------------------

struct to_camera_packet {
	char mode; 			//can be {0,1} indicating mode1 or mode2 operation
	char mode1cmd; 	//defined in set MODE1COMMAND
	float pitch;		//0.00 to 360.00 degrees of pitch
	float yaw; 			//0.00 to 360.00 degrees of yaw
};

if mode is mode1 then camera motion is operated by a joystick device
if mode is mode2 then camera motion is operated by giving pitch
and yaw angles to move to.

NOTE: need to figure out how floats are defined in C for QNX and Java.
NOTE: need to send stop before moving to new direction.

MODE1COMMAND:
	00 - stops every motor
	{02 03 04,
	01 00 05,
	08 07 06} indicates position of hat, or joystick device
	0xA0 - Zoom in
	0xAF - Zoom out
	0xB0 - Iris open
	0xBF - Iris close
	0xC0 - focus plus
	0xCF - focus minus
	0xF1 - toggle light
	0xF2 - toggle camera power

The above will be communicated through a fifo on the SBC located at:
/tart/to_camera_fifo

---------------------------------
From the camera
---------------------------------
This struct is used by the control station to as the relative viewing
angle of the camera with respect to TART.

struct from_camera_packet {
	float pitch;
	float roll;
	float yaw;
};

This info will be communicated through the fifo residing on the SBC
located at:
/tart/from_camera_fifo
