Ensure the connection is made correctly as shown in Figure 3.2. Make sure
the IDE cable is connected to JP2 of the DE2 board.
Download the bitstream (DE2_CCD.sof/pof) to the DE2 board.
Connect the VGA output of the DE2 board to a VGA monitor.
Set toggle switches SW10 and SW9 to ON(UP position); set the other
switches to OFF(DOWN position)
Press KEY0 on the DE2 board to reset the circuit.
You can press KEY3 to switch to the FREE RUN mode and you should be
able to see whatever the camera sees on the VGA display.
Press KEY2 to take a shot of the photo; you can press KEY3 again to switch
back to FREE RUN mode.
If you find the image shown on the display is too dark, you can

number
press KEY1 to reload the new exposure value defined by SW[15:0]
If the room is very dark, you might need to set SW11 to ONE (very long
exposure time).
